“…For ~49Ho decay it was shown [14] that this is not the case, which again will increase the Qp derived from the measured EC/fl + ratio. The Q#values of the doubly even N = 82 isotones of Dy and Er have also been measured, and for 148Dy decay fi+-endpoint and EC/fl + ratio data give consistent results (cf.…”

Using a 14SGd radioactive target and the (p, d), (d, t), and (3He, c~) single neutron pick-up reactions we have measured the 147Gd mass excess as -75,366(4)keV, which differs by 139(24) keV from the adopted value of the 1983 mass table. From this result, and from recently reported first transfer-reaction mass determinations for 14SEu and 146Eu, we have recalculated the masses of nuclei above 146Gd from a previous shell model analysis of high-spin states.

“…The intrinsic detector resolution for ~-3 MeV protons can be safely estimated to be 8 + 1 keV FWHM, mainly based on a separate measurement of discrete proton lines in the decay of 147Dy [10]. There the recoil broadening is about 1 keV only, because of the much heavier mass of the daugther nucleus.…”

Abstract. In high-resolution measurements of delayed protons following the/?-decays of 32Ar and 33At we have observed significant line broadening caused by the/?-v recoil motion of the daughter nuclei. The measured line shapes agree well with the calculation for both Fermi and Gamow-Teller decays and yield new spectroscopic information on the transitions and excited states involved. For the Gamow-Teller strength in the/?+-decay of 33Ar to the isobaric analogue state in 33C1 an upper limit of B~T < 0.029 was determined.

“…In the N=81 nuclei 145Gd, 14VDy and 149Er, the neutron single hole states sl/2 and d3/2 are lowest lying, with vh-111/2 isomeric states, decaying by M4 transitions, some 700 keV higher in excitation energy [1][2][3]. The neighboring odd-odd N= 81 nuclei have each two/% decaying isomers [4], one with U = 1 +, the other with U = (5 ___ 1)-.…”

Following reactions induced by 245 MeV 6~ ions, isomers have been identified in the odd-odd N=81 isotones 146Tb, 148Ho and lS~ with half-lives of 1.18(2), 2.35(4) and 5.2(3) ms, respectively. Their decays have been characterized by y-ray spectroscopy.The isomers are interpreted as (nhll/2vh~/2) lO + states decaying to members of nhlt/2 vd~/i2 and nht~/2 vs?/~ multiplets. The observed level spectra and M1 branching ratios are found to be in good agreement with shell model predictions based on empirical and Schiffer-True n v-~ residual interactions.
