【 摘 要 】

Strong field dissociative ionization of the D2+molecule in the multiphoton regime is investigated employing ab initio calculations for fixed molecular axis orientations. The resulting joint (photoelectron and nuclear kinetic) energy spectra are explored. The number of photons absorbed in each multiphoton peak of these spectra is determined analyzing the angular distribution of the photoelectrons, while the exact path followed by D2+is identified studying the time evolution of the nuclear wave packets.
