Photoionization study using few attosecond pulses and coincidence imaging techniques
Photoionization is one of the most fundamental photoreactions that leads to the ejection of an electron and the formation of an ion. With the help of modern 3D momentum imaging spectrometers, the interplay between the time and frequency domain upon ionization is studied. In this work, single photoionization of helium is investigated in the few-cycle pulse regime of the driving infrared laser pul
