Fully differential study of interference effects in the ionization ofH2by proton impact

“…Over the last 10-15 years kinematically complete experiments (i.e., experiments which determine the momentum vectors of all particles in the system under investigation) revealed that the description of the spatial and temporal evolution of systems as simple as two positively charged ions interacting with an electron represent a formidable theoretical challenge [e.g., [1][2][3][4][5][6][7][8][9][10][11][12]. The basic problem is that the Schrödinger equation is not analytically solvable for more than two mutually interacting particles, even when the underlying forces are precisely known.…”

“…Indeed, qualitative discrepancies between calculated and measured fully differential cross sections (FDCS) for ionization of helium were observed even in the case of very fast projectiles [e.g., 1,6,12], which were thought to represent a relatively "easy" case. For smaller projectile speeds, and especially for larger charge states, the discrepancies become even larger [e.g., 3,4,9].…”

“…A lesser number of papers [14,18,20,23,24,28,29,31,33,[35][36][37][38][39][40][41] have been devoted to the more extreme system Au 53+ + He where the projectile interaction with the He target is very much stronger. Bridging the strength gap, there has also been work on single ionization of He by Au 24+ [23,28,31,39,41].…”

“…A lesser number of papers [14,18,20,23,24,28,29,31,33,[35][36][37][38][39][40][41] have been devoted to the more extreme system Au 53+ + He where the projectile interaction with the He target is very much stronger. Bridging the strength gap, there has also been work on single ionization of He by Au 24+ [23,28,31,39,41]. The experimental studies have ranged from single differential cross sections to double differential cross sections, but only in recent years have fully differential measurements become available [19][20][21][22][23][24][26][27][28]39].…”

“…The theoretical work that was carried out on the C 6+ and Au 24+/53+ systems has been dominated by the continuum distorted-wave eikonal-initial-state approximation (CDW-EIS) [1][2][3][4][5][6][7][8][9][10][11]18,21,23,25,27,[30][31][32][33]35,39,40], its earlier CDW incarnation [11,14,16,17,22,37], or related approximations [19,21,26,27,39,41], and by the classical trajectory Monte Carlo method (CTMC) [7,10,[12][13][14][15][16]19,[35][36][37][38]. Clearly, therefore, there is scope for a fresh approach.…”
