The N=47 Shellmodel Nucleus 90Tc
(1994) In Zeitschrift für Physik A Hadrons and Nuclei 349(2). p.105113 Abstract
 Lifetimes of high spin states in the nucleus Tc90 have been measured via the fusion evaporation reactions Ni58(Ar36, 3pn)Tc90 at 140 MeV and Ni58(Cl35, 2pn)Tc90 at 120 MeV beam energy. The OSIRIS spectrometer as well as a new neutrongammacoincidence setup were used to measure lifetimes in the 10(12)  10(9) s range by the recoil distance Dopplershift method. By means of gammamultiplicity and neutrongated spectra fifteen lifetimes were deduced. The experimental branching ratios and transition probabilities are compared to predictions of shell model calculations in a restricted pi(p(1/2)), pi(g(9/2)), nu(p(1/2)), and nu(g(9/2)) configuration space. In most cases the agreement with the calculations using the GrossFrenkel... (More)

In most cases the agreement with the calculations using the GrossFrenkel parameters is striking but the results for several yrare states very sensitively depend on the residual interaction used.
