Investigation of Kr2+(1S0,1D2)+He(1S0)→Kr+(2P3/2,2P1/2)+He+(2S1/2) charge exchange in crossed beams at collision energy lower 1 eV

The scattering diagrams of Kr+ ions, which are products of Kr2+ charge exchange on He at collision energy of 0.31 and 0.5 eV (in the center-of-mass system) are measured. The typical peaks (''crests'') in the diagrams correlate well in energy with Kr+(2P3/2) and Kr+(2P1/2) ions - products of charge exchange of Kr2+(1S0) - and with Kr+(2P3/2) ions - products of charge exchange of Kr2+(1D2) on He. The measured relations between total cross sections of products formation in the above-mentioned states are in good agreement with the results of previous evaluation experiments
