After the interaction of a
xenon atom with two photons from an attosecond pulse (purple), the
atom is ionized and
multiple electrons (green balls) are ejected.
Abstract: We have investigated multiphoton
multiple ionization dynamics of argon and
xenon atoms using a new x-ray free electron laser (XFEL) facility, SPring - 8 Angstrom Compact free electron LAser (SACLA) in Japan, and identified that highly charged Xe ions with the charge state up to +26 are produced predominantly via four - photon absorption as well as highly charged Ar ions with the charge state up to +10... ▽ More We have investigated multiphoton
