The timedependent HartreeFock method within a Gausslobe basis and application to protonHe collisions
Abstract
For the description of ionatom collisions in the semiclassical approximation the timedependent HartreeFock (TDHF) method is used. The TDHF equations are solved by expanding the electron wave functions within a basic set of Gausslobe functions. On this basis the matrix elements of the TDHF Hamiltonian can be obtained analytically, even if translational factors are included. As an application the excitation cross sections of the (1s2s) 1S and (1s2P) 1P states of He in protonHe collisions are calculated.
