Lifetimes of superdeformed rotational states in [Formula Presented]
Lifetimes have been measured in a superdeformed rotational band recently identified in the [Formula Presented] nucleus [Formula Presented] A large low-spin quadrupole deformation [Formula Presented] is confirmed and a decrease in the collectivity is observed as the high-spin band termination at [Formula Presented] is approached. Detailed comparisons of the experimental [Formula Presented] values w
Gympalärare, idrottslärare eller lärare i Idrott och hälsa : Benämningen av ämnet och det förväntade innehållet
Skolämnet Idrott och hälsa (IDH) har ett brett innehåll eftersom det inkluderar både idrottsaspekter och hälsoaspekter. Tidigare studier har visat att idrott-delen dominerar på flera sätt, delvis på grund av ett vagt och icke-specifikt ämnesspråk i ämnesplaner, kursplaner och läromedel (Lundin & Schenker 2021, 2022; Lundin m.fl. 2021, 2023). Detta resulterar i att hälsoaspekterna av ämnet inteThe school subject Physical Education and Health (PEH) has a wide scope with respect to its content, combining the aspects ‘sports’ and ‘health’. Previous studies have shown that for the Swedish school subject PEH, sports dominate the content of the subject in several aspects, as a result of, for instance, a vague and unspecific subject specific literacy used in the curricula and course books (Lun
Fast rotation of the N = Z nucleus 36Ar
A highly-deformed rotational band has been identified in the N = Z nucleus 36Ar. At high spin the band is observed to its presumed termination at Iπ = 16+, while at low spin it has been firmly linked to previously known states in 36Ar. Spins, parities, and absolute excitation energies have thus been determined throughout the band. Lifetime measurements establish a large low-spin quadrupole deforma
The uses of the term polarisation in Swedish newspapers, 2010–2021
In this article, we investigate the rhetorical uses and media frames associated with the term polarisation in Swedish print media from 2010 to 2021. We first produce a qualitative and detailed assessment of a sample of 240 articles and then proceed to a computational (word2vec) analysis of all major Swedish newspaper articles including the term (N = 32,805). We find that the term has changed its r
Collective rotational motion in the N=Z nucleus 36Ar
A superdeformed rotational band has been identified in the N = Z nucleus 36Ar, firmly linked to known low-spin states, and observed to its high-spin termination at Iπ = 16+. Lifetime measurements by the Doppler shift attenuation method establish a large low-spin deformation (β2 ≈ 0.46) and a decrease in the collectivity as the band approaches termination. Comparisons with cranked Nilsson-Strutinsk
High-spin terminating bands formed from successive particle-hole excitations across closed shells
Observed high spin states in 30Zn and 66Dy isotopes with two protons outside the closed shells at Z = 28 and Z = 64, respectively, are discussed and compared with cranked Nilsson-Strutinsky calculations. Bands terminating at higher and higher spin values are formed from successive proton excitations across these shells. These bands show very different features depending on the number of excited pa
New γ transitions in 27Na from 14C on 14C
The neutron rich 27Na was studied at Florida State University using the 14C(14C,p) reaction at 22 MeV. The 14C target was 0.28 mg/cm2 thick. γ-γ and particle-γ, coincidences were measured using 2 four-crystal clover detectors, 7 Compton-suppressed HPGe detectors, and a particle detector telescope at 0°. The 1757, 1823, and 2219 keV transitions are likely yrast transitions in 27Na. Based on systema
First evidence for smooth band termination in valence space in the mass 130 region : Spectroscopy of 127La
High spin states in 127La have been studied using the 32S(100Mo,p4n) reaction at a beam energy of 155 MeV. Gamma rays were detected using the EUROBALL III spectrometer. One of the side bands in 127La is observed to be populated to a spin of 83/2+. These data are compared with cranked Nilsson-Strutinski calculations which suggest that the structure is a smoothly terminating band, in valence space,
Identification of excited states in 119Ba
Excited states have been identified in the very neutron-deficient 119Ba nucleus. Two bands have been observed, which are likely to be based on h11/2 and (g7/2d5/2) neutron orbitals. Despite this being the first observation of excited states in 119Ba, the bands extend to (75/2)ℏ and (79/2)ℏ, respectively. The bands have been assigned to 119Ba using gamma-recoil and gamma-x-ray coincidences. Several
The frequency of atrial fibrillatory waves is modulated by the spatiotemporal pattern of acetylcholine release : a 3D computational study
In atrial fibrillation (AF), the ECG P-wave, which represents atrial depolarization, is replaced with chaotic and irregular fibrillation waves (f waves). The f-wave frequency, F f, shows significant variations over time. Cardiorespiratory interactions regulated by the autonomic nervous system have been suggested to play a role in such variations. We conducted a simulation study to test whether t
Many-photon effects in time-resolved second harmonic generation from systems in optical cavities
Second harmonic generation is popular due to its numerous applications in different technologies dealing with multiple fields of science. The rapid technical advancement with the second harmonic generation demands parallel development in the theoretical understanding. With this view in mind, in our three papers, we theoretically investigated second harmonic generation from different systems in an
Collective structures and band termination in 107Sb
High-spin states in the near proton-dripline nucleus 107Sb have been identified, and collectivity in this nucleus has been observed for the first time in the form of two rotational bands. One of the observed rotational structures is a ΔI = 1 band, and is interpreted as based on a π(g9/2)-1 ⊗ π(g7/2d5/2)2 proton configuration. A second structure has ΔI = 2 character, and is explained as being based
Terminating bands in 98,99,100Ru nuclei : New information on the neutron 2d5/2 and 1g7/2 energy spacing
High-spin states of 98,99,100Ru have been populated using the reaction 70Zn(36S, αxn) at 130 MeV. The γ rays have been detected with the EUROGAM-2 array. New high-spin bands have been established in these nuclei and interpreted as terminating configurations using the Nilsson-Strutinsky cranking formalism. These bands were observed up to the predicted terminating states which are built from g9/2 pr
Discrete line γ-ray spectroscopy in the (50-60)ℏ spin domain of 161,162Er
Very high spin states (I=50-60ℏ) have been observed in the transitional nuclei 161Er and 162Er using the Euroball γ-ray spectrometer. In 161Er, three bands are observed well above spin 50ℏ. In the positive parity, positive signature (+, + 1/2) band a discontinuity in the regular rotational behavior occurs at 109/2+ and a splitting into two branches occurs at 97/2- in the negative parity, positive

The interpretation of verbal moods in Spanish : A close replication of Kanwit and Geeslin (2014)
This study is a close replication of Kanwit and Geeslin (2014), an investigation of the interpretation of verbal moods in adverbial clauses in Spanish. Whereas the first language of the second-language participants in the original study was English, we explore whether Kanwit and Geeslin’s results extend to other first-language populations—Swedish and French learners of Spanish. Participants in the
