MAGNETIC-FIELD EFFECTS ON ELECTRON-CAPTURE PROCESSES BY HIGHLY-CHARGED IONS - COLLISIONS OF B4-ATOMS( IONS WITH H)

The electron capture processes in collision of highly charged ions wit h neutral atoms in a strong magnetic field are investigated in the cas e of arbitrary held direction. A semiclassical molecular-orbital close -coupling method is employed. The phase factors arising from the elect ron translation factor and the gauge transformation are included. We a pply this method to the singlet (B4+ + H) system which have been inves tigated previously by us only for the held direction being along with the incident velocity vector. The total cross section averaged over he ld direction increases with held strength. When the held direction is perpendicular to the collision plane, the held effects become maximum.
