Excited states of97Pd

Excited states in 97Ag have been identified for the first time following the reactions 46Ti(SSNi, ep2n) and 64Zn(36Ar, p2n). The population cross sections were 1.0(5)mb and 0.7(3) rob, respectively. The y-decay of the seniority v = 3 states below the I~= (17/2-) and (21/2 +) isomers was investigated. In a search for short lived isomers half lives of t1/2=5(2 ) ns and 2.5(5)ns were found in the N=50 isotones 97Ag, U=(17/2-) and/or (21/2 +) and 95Rh, U=(21/2+). A new isomer was identified in 9Vpd, U=17/2 + with tl/2 = 2.3 (5) ns. The implication of the three-proton hole spectrum in ~~176 for the empirical residual interaction and shell model predictions is discussed.

High spin states in 97Rh were excited via the 96Ru (c~,2np) reaction at 45MeV. As a main finding we have observed a positive parity band, built on the 9/2 + ground state, which depopulated levels at 3,550.7 (25/2+), 3,259.1 (23/2+), 2,895.1 (23/2+), 1,961.3 (19/2+), 1,553.1 (17/2 + ) and 857.1 (13/2+). Also we have excited levels at 3,055.8 (21/2), 2,225.4 (17/2) and 1,463.5 (15/2), which most likely ar e negative parity states.

Excited states of97Pd

Abstract: The 97pd nucleus has been studied from the reaction 96Ru(3He, 2n)97pd. From in and out beam direct ~,-spectra and ~'-7 coincidences a partial level scheme is proposed. The observed high spin states can be explained by the coupling of the even proton core with the d~/2 51" neutron.
