Electron capture with He2+, Li3+, Be4+and B5+projectiles from atomic hydrogen

Electron capture from atomic hydrogen into orbitals of fully stripped ions (helium to boron) is investigated at impact velocities between 0.3 and 1.4 au. The authors report the summed total cross sections for electron capture into the states of the incident nucleus, obtained by solution of the time-dependent Schrodinger equation in terms of a basis set of the Hylleraas type with a straight-line approximation for the nuclear motion.
