Tables of Shore and Fano parameters for the helium resonances [formula omitted], [formula omitted], and [formula omitted] excited in p-He collisions Ep = 33–150 keV

Abstract

Absolute values of Shore and Fano parameters are tabulated for the helium atom 2s 2 1S , 2p 2 1D , and 2s 2p 1P resonances produced by a proton beam. Observations were made on the spectra of ejected electrons. The important variation of the shape of the resonances with ejection angle is illustrated for E p = 100 keV; the variation with proton energy is shown at 30°.
