β-decay feeding intensity distributions of 71, 73Ni
RADIOACTIVITY 71,73Ni(β-)[from 9Be(86Kr, X), E=140 MeV/nucleon, followed by separation of fragments using A1900 fragment separator at NSCL-MSU facility]; measured implantation events and β particles using position-sensitive, double-sided, silicon-strip detector (DSSD), and two silicon PIN detectors for TOF and energy loss, Eγ, Iγ, half-lives of decays of 71,73Ni using a total absorption summing NaI(Tl) detector (SuN) surrounding the DSSD; deduced multiplicity spectra, Iβ(E) feedings, B(GT). GEANT4 and DICEBOX analysis of total absorption spectrum (TAS). Comparison with QRPA, and shell-model calculations, the latter using NuShellX@MSU code with JJ44B and JUN45 interaction Hamiltonians. Relevance to improvement in the nuclear input for r-process calculations.
NUCLEAR REACTIONS 9Be(86Kr, X)71Ni/73Ni/71Cu/73Cu/, E=140 MeV/nucleon; measured yields of reaction products using A1900 fragment separator and two silicon PIN detectors for TOF and energy loss at NSCL-MSU facility.
