Mass Chain Evaluation for A=95

A full evaluation of the mass chain A = 95 has been done in the ENSDF format taking into account all the available data until June 2009. Excited states populated by in-beam nuclear reactions and by radioactive decay have been considered. The 'evp' editor, developed at the NNDC, has been used for the evaluation. This mass chain was last evaluated in 1993. Many new and improved data were reported since then. A total of 13 nuclei have been evaluated.

Nuclear Data Sheets for A = 95

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 {sup 95}Ag 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 {sup 95}Ag has been reported for the first time (2003Ma24). A comprehensive level scheme {sup 95}Pd is now available through the ? decay of {sup 95}Ag (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 {sup 95}Rh has been extended up to 39/2 h by in-beam spectroscopy (1994Ro08) and the {gamma}-delayed proton decays from 96Ag isomers to low-lying levels in {sup 95}Pd have been observed (2003Ba39). The high spin level scheme of {sup 95}Ru has been extended up 43/2 h (1994Gh06) and the lifetime or lifetime limits of several high spin states have been reported (2004Ga08). In {sup 95}Tc, the level scheme has been extended by in-beam spectroscopy (2000Gh01). New data on high spin states in {sup 95}Mo have been available through in-beam spectroscopy using heavy ion reactions [(1998Kh04),(2004Ch18),(2009Zh11)]. The data on {sup 95}Nb has been considerably extended by (t,p) reaction (2005Ra30) and by ({sup 82}Se,p2n{gamma}) reaction (2005Bu08). In {sup 95}Zr, new measurements on {mu} (2005St24) and Q (1998Se01) have become available. Controversy on the existence of a 23 keV state in {sup 95}Zr 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 {sup 95}Y by n-induced and spontaneous fission decay have been available (2009Ur02). High spin data on {sup 95}Sr have been reported by {gamma}-spectroscopy of spontaneous fission decay (2004Hw04). In {sup 95}Rb, revised estimate of {gamma}-n decay intensity (2002Pf04) and mass excess (2007Ra23) have been reported. New data on {sup 85}Kr it decay have been reported [(2006Ge05),(2007Si17)] and incorporated.
