Beta + decay of 15.2-min 114Te.

Abstract

The ${\mathrm{\ensuremath{\beta}}}^{+}$ decay of 15.2 min $^{114}\mathrm{Te}$ into levels of $^{114}\mathrm{Sb}$ was studied through \ensuremath{\gamma}-ray and conversion electron spectroscopy at the UNISOR on-line isotope mass separator. Multiscaled \ensuremath{\gamma}-ray and electron singles provided for the determination of energies and intensities for 94 transitions (68 new) and of internal conversion coefficients for 12 of these transitions. The level scheme was deduced from \ensuremath{\gamma}-\ensuremath{\gamma} and \ensuremath{\gamma}-e coincidence measurements and extended to 2.1 MeV. The energy spectrum and electromagnetic properties of levels and associated transitions were calculated in the interacting boson-fermion-fermion model (IBFFM), with good agreement between experimental and theoretical results. \textcopyright{} 1996 The American Physical Society.
