CHARGE-TRANSFER PROCESSES INVOLVING HIGHLY EXCITED HYDROGEN-ATOMS .2. NUMERICAL RESULTS BY THE BORN APPROXIMATION

The cross sections for the charge transfer processes p+H(ns)→H(n′ s, n′ p)+p are calculated through the Born approximation formulated in paper I of this series. The cross sections show oscillatory structures at low energies which result from the nodes of the atomic wave functions in the momentum space. The oscillations of the full Born cross sections are more remarkable than those of the Brinkman-Kramers cross sections. The momentum transfer effect of the electron becomes more important down to lower energies as n increases. A new interpretation of this effect is given which is based on the momentum distribution of the atomic electron. © 1979, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
