Nuclear Data Sheets for A = 95

Abstract

Experimental data on ground and excited state properties for all known nuclei with mass number A=95 have been compiled and evaluated. States populated in radioactive decay, as well as in nuclear reactions, have been considered. For these nuclei, level and decay schemes, as well as tables of nuclear properties, are presented. This work supersedes the 1993 evaluation by T. W. Burrows (1993Bu08). In summary, three isomers were identified in 95Ag and their respective decay schemes were presented (2003Do09) though only limits on their half lives could be obtained. Besides, high resolution prompt gamma-spectroscopy of 95Ag has been reported for the first time (2003Ma24). A comprehensive level scheme 95Pd is now available through the ε decay of 95Ag (2005Ha45) and the energy of the 21/2+ spin-gap isomer have been established for the first time by observing the gamma-rays from the yrast levels (2003Ma24). The level scheme of 95Rh has been extended up to 39/2 h by in-beam spectroscopy (1994Ro08) and the γ-delayed proton decays from 96Ag isomers to low-lying levels in 95Pd have been observed (2003Ba39). The high spin level scheme of 95Ru has been extended up 43/2 h (1994Gh06) and the lifetime or lifetime limits of several high spin states have been reported (2004Ga08). In 95Tc, the level scheme has been extended by in-beam spectroscopy (2000Gh01). New data on high spin states in 95Mo have been available through in-beam spectroscopy using heavy ion reactions [(1998Kh04),(2004Ch18),(2009Zh11)]. The data on 95Nb has been considerably extended by (t,p) reaction (2005Ra30) and by ( 82Se,p2n γ) reaction (2005Bu08). In 95Zr, new measurements on μ (2005St24) and Q (1998Se01) have become available. Controversy on the existence of a 23 keV state in 95Zr has been resolved by a high-resolution measurement using magnetic spectrometer (2003So23). New data on high spin states have been published through heavy-ion induced fission [(2002Fo03), (2005Pa48)]. Very recently, new high spin data on 95Y by n-induced and spontaneous fission decay have been available (2009Ur02). High spin data on 95Sr have been reported by γ-spectroscopy of spontaneous fission decay (2004Hw04). In 95Rb, revised estimate of γ-n decay intensity (2002Pf04) and mass excess (2007Ra23) have been reported. New data on 85Kr it decay have been reported [(2006Ge05),(2007Si17)] and incorporated.
