摘要：

Proton emission has been observed from the new isotope 146Tm. Two transitions have been identified at energies of 1119 +/- 5 keV and 1189 +/- 5 keV corresponding to Q-values of 1127 +/- 5 keV and 1197 +/- 5 keV respectively. The measured half-lives of 2 35 +/- 27 ms and 72 +/- 2 3 ms are well reproduced by simple WKB calculations assuming proton emission from h11/2 orbitals. The proton transitions are assigned to a 10+ isomeric state and a low lying 5- or 6- level.
