lntegrai total and Integral iomzatlon cross sections of fle"(2 3S)-Ar and He\*(Z 'S)-Ar have been measured in the c-m. collision energy range 2-230 meV. The data are compared with optxal potentid ulculations givmz prelimmary fits which are discussed.
The effect of laser polarization on the laser-assisted He+ ion signal is Investigated cxpcrimentally in order to check existing thcorctical calculations. Two important features are deduced from the data: First, the laser-assisted cross section is essentially the same for laser polaruation parallel o
Separate Penning election spectra were measured resulting from the ionbation of H ator& by He(Z'S) and Hc(~~S) metastables in thermal collisions. From these results potential parameters of the dhtomics .&(2'S)-H('S) ('C) and He(23S)-H('S) (7 z) as well as the cross-section ratio uQinglet)/o(tripIet)
