“…The data in the column "experiment" are from[18,19,[22][23][24][25] For the 1,605.2 keV and 1,902.3 keV levels this agrees with previous measurements 1-19], 1 = (3) and l = 4 respectively.…”

“…The following discussion has therefore to be regarded as tentative. The assignment for the 2,716.4 keV level disagrees with the /=3 reported in [19,25]. The 3/2-assignment has some preference because this level is also fed by 7-rays from the 9/2 + decay.…”

“…The 1,155.8keV level has been assigned 3/2(1/2) . This is apparently not the same as the 2,883 keV level with l= 1 seen in the (p, d) reaction [25]. It is in agreement with the 3/2-assignment concluded from (p, d) studies [19].…”

Decay studies on a number of short-lived odd nuclei in the N = 50 region are described.The 59.6-s 93Ru ground state decay was studied in detail for the first time; in these experiments the 10.8-s activity 93mRu was discovered. The 91Tc activities were also observed for the first time. The ground state and an isomeric state of this nucleus decay with nearby equal half-lives (3.14 and 3.3-min). The activities 91gMo (16.6-min) and 9S"Mo (65.1-s) have been reinvestigated. A number of v-rays, previously erroneously assigned to the 91Mo activities, could be eliminated. A strong similarity is noted for the decay schemes of the N=49 isotones 91mMo and 93mRU. The energy of the 1/2-isomeric state in 93Ru and the B(M4)-value of the isomeric transition fit well into the systematics of the previously known N = 49 isotones.

“…The QRPA-Biehle prediction relies on the nearby nuclei 88,90 Mo, 92 Ru, and 94 Pd, which do not exhibit the same level (2.1 ≤ R 4/2 ≤ 2.23) [14,15,16,17] of deformation observed in the N = Z region near A = 80 but ap-proach spherical shapes, lengthening the predicted halflives. The self-consistent parameters for the QRPA-Sk3 and QRPA-SG2 cases were derived from experimental data from nuclei in the region of interest, and mostly reproduce the experimental half-lives using self-consistent deformations that minimize the energy.…”

A half-life of 2.2 ± 0.2 s has been deduced for the ground-state β decay of 84 Mo, more than 1σ shorter than the previously adopted value. 84 Mo is an even-even N = Z nucleus lying on the proton dripline, created during explosive hydrogen burning in Type I X-ray bursts in the rapid proton capture (rp) process. The effect of the measured half-life on rp-process reaction flow is explored. Implications on theoretical treatments of nuclear deformation in 84 Mo are also discussed. FIG. 1: Yrast states up to 8 + in even-even N = Z nuclei. The transition energies are given in MeV. R 4/2 ratios are shown just below 0 + state. Taken from [10, 11].

“…Many papers have been devoted to the study of nuclei with neutron number close to N=50 (Vlasov et a1 1960, Kaptein et a1 1976, Gerlic er a1 1975, Gales et af 1977, Van de Wiele et a1 1978, Duhamel et af 1981, Massolo et af 1982. It is interesting that the first data on the deep hole states of Zr isotopes were obtained as long ago as 1960 (Vlasov et a1 1960).…”
