The average energy (W) expended per ion pair (ip) in hydrogen and the number of molecular singlet (R/sub 2/) and triplet (R/sub 3/) excitations pe r ion pair were calculated for electrons of up to 1500 eV energy and extrapolated to high energy limits. Experimental and theoretical cross ectron energy distribution based on measurement of Opal, Beaty, and Peterson at 500 eV and for the Gryzinski distribution. For each distribution calculations were made for two assumptions concerning dissociative ionizastion. For the preferred calculation (experiment-based secondary electron distribution for ordinary ionization and zcro kinetic energy for electrons formed in dissociative ionization) the results at high energies are W = 36/sub .8/ eV/ip, R/sub 2/ = 1.0/sub 6/ (includes dissociative excitatio n), and f W is 36.3 eV/ip.
