description

Publisher Summary This chapter discusses collision processes in the presence of a strong magnetic field. The chapter deals with the potential scattering in a magnetic field arising in connection with the problem of Bremsstrahlung (“free–free transitions”) of an electron in the field. An expression for the photoionization cross section of a one-electron (hydrogenic) system in a magnetic field is also presented. A different approach is required to the problem of ion–atom collisions in a magnetic field because the collision energy E is generally much greater than hωc. Within the two-state model, not only did the magnetic field modify the bound-state wave functions, but, more importantly, it introduces a new phase factor in the matrix elements. This acts in a similar way to the well-known momentum-transfer factor in damping the transition probability oscillations and sharply reducing the cross section.
