Description
The proton decay of the highly deformed nucleus 135Tb has been observed following bombardment of a 92Mo target with a 310 MeV beam of 50Cr ions. This is the first instance of a proton-decaying isotope being produced via the 1p6n fusion-evaporation channel. Evaporation residues were separated in-flight using the Argonne fragment mass analyzer and implanted into a new design double-sided silicon strip detector. 135Tb decays by the emission of a proton with energy Ep=1179(7) keV [Qp=1188(7) keV] and half-life t1/2=0.94-0.22+0.33ms. The transition is assigned to a highly deformed (β2∼0.3) Jπ=7/2- configuration by comparing the proton decay rate with calculations for deformed nuclei
