Description
The behaviors of CH2He+ and C2H5He+ formed by the decay of CH3T and C2H5T were studied theoretically using the STO-3G molecular orbital method and was compared with that of HHe+ in the decay of HT. It was clearly shown that the ground state daughter ions CH3He+ and C2H5He+ dissociate instantly to give CH3+ and C2H5+ because their potential energy curves are repulsive, whereas the daughter ion HHe+ in the ground state does not dissociate. The transition probability to the ground state ions of CH3He+ and of C2H5He+ are computed to be 66.5 and 64.8%, respectively. These values are in fairly good accordance with those obtained experimentally. (auth.)
