Cross Sections for Spin Exchange Collisions Between Fast Hydrogen Atoms and Hydrogen or Alkali Atoms

摘要

Spin exchange cross sections have been calculated for hydrogen atoms with energy in the keV range incident on hydrogen or alkali atom targets. The cross sections generally decrease with increasing energy, but also show oscillations as a function of the energy. For a hydrogen atom with an energy of 5 keV incident on a sodium atom target, the total spin exchange cross section is 1.2 x 10 sup -15 cm sup 2 . 15 refs., 1 fig. (ERA citation 11:024309)
