“…To some extent this is confirmed by our limited shell model study. The emergence of the experimentally observed first negative-parity state J π = 11/2 − has been linked to the 1h 11/2 intruder configuration [46]. A lowering of level energy due to the admixture of intruder configurations explains why the shell model predicts this and some other states to be higher in energy.…”

The emission of γ rays from neutron-bound and neutron-unbound states in 95 Mo, populated in the 94 Mo(d,p) reaction, has been investigated. Charged particles and γ radiation were detected with arrays of annular silicon and Clover-type high-purity Germanium detectors, respectively. Utilizing proton-γ and proton-γ-γ coincidences, the 95 Mo level scheme was greatly enhanced with 102 new transitions and 43 new states. It agrees well with shell model calculations for excitation energies below ≈2 MeV. From proton-γ coincidence data, a new method for the determination of spins of discrete levels is proposed. The method exploits the suppression of high-angular momentum neutron emission from levels with high spins populated in the (d,p) reaction above the neutron separation energy. Spins for almost all 95 Mo levels below 2 MeV (and for a few levels above) have been determined with this method.

“…Contamination was a problem for the 88 Sr and 90 Zr targets, so additional angles of 10 • and 22.5 • were used for the α-induced reaction to reveal all states for at least one angle. Angular-momentum assignments for the majority of the states populated have been made in previous work [7][8][9][10][11][12][13][14][15][16][17][18][19]; these were checked using measured angular distributions and information gained by a comparison of cross sections from the two different reactions used.…”

Neutron single-particle strength outside theN=50core

et al. 2013

The single-neutron properties of N = 51 nuclei have been studied with the (d,p) and (α, 3 He) reactions, at beam energies of 15 and 50 MeV respectively, on 88 Sr, 90 Zr, and 92 Mo targets. The light reaction products were momentum analyzed using a conventional magnetic spectrometer. Additionally, the 2 H(86 Kr,p) reaction was measured at a beam energy of 10 MeV/u, where outgoing light ions were analyzed using a helical-orbit spectrometer. Absolute cross sections and angular distributions corresponding to the population of different final states in the heavy product were obtained for each reaction. Spectroscopic factors were extracted and centroids of the single-particle strength were deduced. The observations appear consistent with calculations based on an evolution of single-particle structure driven by the nucleon-nucleon forces acting between valence protons and neutrons.

“…11/2 level at 2070 keV has been observed in a Sr(d,p) reaction study (66). It seems improbable that the 2058.0-keV level is either a 9/2* or 11/2 since these spin and parity assignments would be likely to render beta decay to this level unobservable.…”
