摘要: Excited states in 3 transitional proton emitters 145,146,147Tm were studied using the Gammasphere Ge array coupled with Argonne Fragment Mass Analyzer. The 147Tm level scheme was extended and unfavored signature partner of decoupled h 11/2 band found. A rotational feeding high-spin isomer 146Tm observed properties similar to ground-state band. regular sequence γ rays correlated 145Tm decay has as well. In addition, coincidences between fine structure line 2+ → 0+ γ-ray transition daughter nucleus detected. Comparison energies measured calculated Particle Rotor model indicates that might be γ-soft.
