Proton emission has been observed from the new isotope Tm. 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 235±27 ms and 72±23 ms are well reproduced by simple WKB calculations assuming proton emission from h orbitals. The proton transitions are assigned to a 10 isomeric state and a low lying 5 or 6 level.
