“…The electron transfer to the projectile can proceed via different reaction channels: (a) electron-electronThomas TI (eeTTI) Palinkas et al, 1989;Briggs and Taulbjerg, 1979;Ishihara and McGuire, 1988;McGuire et al, 1989McGuire et al, , 1995Shakeshaft and Spruch, 1979); (b) nucleus-electron-Thomas TI (nTTI) (Thomas, 1927, Horsdal-Pedersen et al, 1983Vogt et al, 1986); and (c) kinematical capture (KTI) (Brinkman-Cramer type). While eeTTI always leads to a transfer ionization where the second electron is ejected, the KTI and nTTI processes are accompanied by ionization of the second electron either by shake-off via e-e correlation or by an independent binary collision of the proton with the second electron.…”

Many particle dynamics in atomic and molecular physics has been investigated by using the COLTRIMS method. The method and its power is discussed. The COLTRIMS technique visualizes many-particle fragmentation processes in the eV and sub milli-eV regime and reveals like the bubble chamber the complete momentum pattern in atomic and molecular particles reactions. Complete differential cross sections in momentum space have been measured for the transfer ionization channel in fast four-body (p+He-H +He 2+ +e) collisions. The correlated kinematical transfer ionization channel has been used to probe the highly correlated contributions to the asymptotic parts (high momenta and large nuclear impact parameters) of the He ground-state momentum wave function. In this reaction, one electron with selected initial momentum (2.5-7.5 a.u.) in the He ground state is kinematically captured by the proton (tunneling through the two-center barrier). The measured three-particle final-state momentum distributions show well-structured patterns, which reflect special features of the three-particle initial-state momentum wave function. r

“…An excellent review of the theoretical aspects of the ECC process in ionatom collisions has recently been provided by Shakeshaft and Spruch [12]. A number of experimental findings complementary to these discussed here have been covered by Meckbach et al [9].…”

“…Electron capture to the continuum (ECC) has been described, first classically by Thomas[l] in 1927, and subsequently by many authors [2][3][4][5][6] quantum mechanically, as a process in which a high speed bare ion projectile captures an electron from a static target atom. The electron final state is considered to be a projectile centered continuum state, i.e., the electron has essentially zero kinetic energy relative to the projectile ion after the interaction.…”
