Abstract

Excited states in 3 transitional proton emitters Tm were studied using the Gammasphere Ge array coupled with the Argonne Fragment Mass Analyzer. The Tm level scheme was extended and the unfavored signature partner of the decoupled proton h band was found. A rotational band feeding the high-spin isomer in Tm was observed with properties similar to the Tm ground-state band. A regular sequence of γ rays correlated with the ground-state Tm proton decay has properties of the h band as well. In addition, coincidences between the fine structure proton line and the 2 → 0 γ-ray transition in the daughter nucleus were detected. Comparison between level energies measured and calculated using the Particle Rotor model indicates that Tm might be γ-soft.
