“…For instance, if a sufficiently high intensity laser is combined with this technique, it would allow one to perform laser assisted EMS experiments that aim to measure electron momentum distributions in field dressed states. 33 Instead, if one can combine the nonadiabatic alignment method by laser pulse, 34 the momentum space imaging of molecular orbitals in three-dimensional form would become possible. This may be a more general method compared with the electron-electron fragment ion triple coincidence technique, 35,36 although reducing the velocity mismatch effects 37 is to be considered.…”

“…In laser-assisted impact ionization, if the projectile electron and/or the ejected electron absorb or emit photons, then the transition amplitude (10) comprises a sum of terms with each proportional to J l (q · α), where J l is the lth order Bessel function of the first kind, l indicates the number of absorbed or emitted photons, and α is the displacement amplitude of an electron in the laser field [45,56,57]. In our simulations |α| 0.005 a.u., since the laser field used to drive the population transfer in the lithium atom is assumed to have low intensity; see Sec.…”

“…Recently, (e,2e) measurements have been carried out for excited molecular states [43,44]. Recent theoretical advances include analyses and simulations of laser-assisted EMS processes [45] as well as of time-resolved EMS for electronic motions in atoms and molecules [46]. With regard to the latter, the time scale of typical electronic motions ranges from femtosecond (fs) to sub-fs, which exceeds current temporal resolutions of EMS measurements.…”

“…Recently, a new line of research in the field of electronimpact ionization at large momentum transfer has emerged, which is called the laser-assisted EMS [19][20][21]. Currently, an EMS apparatus is being developed for combination with a sufficiently high intensity laser [22].…”
