Abstract

Gamma rays from the decay of states in the proton unstable nucleus [Formula Presented]Tm were observed for the first time following the [Formula Presented]Mo[Formula Presented]Ni, p2n)[Formula Presented]Tm reaction at 260 MeV. Prompt [Formula Presented] rays were detected with an array of Compton-suppressed Ge detectors, placed in front of the fragment mass analyzer at the ATLAS accelerator, and were assigned to individual reaction channels on an event-by-event basis using the recoil-decay tagging method. Gamma-ray transitions were associated with both the proton decay of the [Formula Presented][Formula Presented] ground state and the [Formula Presented][Formula Presented] isomeric state in [Formula Presented]Tm, even though the cross sections for populating these states were only [Formula Presented] 16 [Formula Presented]b and 2 [Formula Presented]b, respectively. The level scheme which was constructed for [Formula Presented]Tm is discussed and compared with the level structures for lighter [Formula Presented]=78 isotones.
