Abstract

The72Ge(α, n)75Se and73Ge(α, 2n)75Se reactions have been studied at bombarding energies of 15 MeV and 22.5 MeV respectively using Ge(Li)-detectors.γ-singles spectra,γ-γ-coincidences,γ-angular distributions and excitation functions have been taken. A level scheme has been constructed, which contains a stretched spin and a normal rotational band.

Nuclear reactions72Ge(α, n)75Se,73Ge(α, 2n)75Se; measuredE γ ,I γ ,γ-γ-coincidences,γ-angular distribution,γ-excitation function.75Se deduced levels,J, π, γ-multipolarity. Enriched target, Ge(Li).

We are indebted to Dr. J. Eberth, who manufactured the Ge(Li)-detectors and thank Mr. H. Bohnhoff and his crew at the Cologne FN-tandem for providing the4He-beam; finally we thank Profs. Z. P. Sawa, K. P. Lieb and A. Gelberg for various useful discussions. We thank also the International Bureau at the GFK and the Rumanian State Commitee for Nuclear Energy, who have made this cooperation possible.
