Abstract / Description of output

Gamma rays from the transitional proton emitting nuclei Tm have been observed using the recoil-decay tagging technique. The ground state band of Tm was confirmed and extended and the unfavoured signature sequence was observed. A ground state rotational band with properties of a decoupled h band was observed in Tm. In addition coincidences between the proton fine structure line and the 2→0 γ-ray transition in Er were detected at the focal plane of the FMA. This is the first time that coincidences between proton radioactive decays and γ rays have been seen. The particle decay of Tm has been measured with improved statistics and a rotational band similar to Tm has been observed.
