Cross sections for the excitation of the 41S-, 41D- and 31P-levels of helium excited by fast He+-ions
- 11 Downloads
An experimental study has been made of the excitation of the 41S-, 41D- and 31-P-levels of helium by fast He+-ions in the energy range of 80 to 1100 keV. Absolute cross sections have been obtained by normalization on proton-impact results. A pronounced broad maximum has been found in the three excitation functions. The results are compared with proton-impact results of equal velocities.
