Balmer-line emission from low-energy H/sup +/ impact on rare-gas atoms
Absolute cross sections for the emission of Balmer-..cap alpha.. radiation have been measured for low-energy H/sup +/ impact on He, Ne, Kr, and Xe atoms. Measurements were made at H/sup +/ energies of 2.0 and 1.25 keV for He, from 2.0 to 0.5 keV for Ne, and from 2.0 to 0.04 keV for Kr and Xe. The Balmer-..beta.. emission cross sections were also measured for Kr and Xe, as were the polarizations of the radiations, and the contributions to the radiations from decay of the 3s and 4s excited states of hydrogen were resolved for H/sup +/ energies above 0.2 keV. The data are compared with similar results for Ar reported earlier, and with the results of other workers at higher H/sup +/ energies.
