Vibrational population factors for the nascent Penning ions HD{sup +}(v)(...He) and energy of the corresponding Penning electrons are calculated for the ionization event He(2{sup 3}S)-HD(v=0){yields}[He...HD{sup +}(v)]+e taking place at range of the He{sup *}-HD separations and orientations accessible by the system during thermal energy collisions. The vibrational population factors are obtained from the local widths of the He(2{sup 3}S)-HD(v=0,N) state with respect to autoionization to HD{sup +}(...He) in its Vth vibrational level. The initial overall picture of the autoionization event is consistent with the He(2{sup 3}S)-H{sub 2}(v=0) one. On the other hand, the vibrational population factors are different from the approximate average populations used in initial model theoretical considerations about the Penning process system. Variation of the calculated quantities with changes in the He{sup *}-HD separations and orientations is found to be smooth enough to guarantee that the present data might form a sound basis for construction of analytical representations of the corresponding 2D surfaces and for future study of the dynamics of the collision system. 17 refs., 3 fig., 2 tab.
