Description
Measurements of γ-ray multiplicities from the 150Sm(α,xn) reactions at beam energies from 40-140 MeV show that the maximum angular momentum transfer occurs at an energy between 12 and 18 MeV higher than that of the maximum of the excitation function for the respective exit channel. At still higher bombarding energies, where precompound processes dominate, a decrease of the multiplicity is observed. (orig.)
Abstract (German)
Messungen der γ-Multiplizitaeten in den Reaktionen 150Sm(α,xn) im Energiebereich zwischen 40 und 140 MeV zeigen, dass das Maximum des Drehimpulsuebertrags etwa 12 bis 18 MeV hoeher liegt als das Maximum der Anregungsfunktion des jeweiligen Ausgangskanals. Bei noch hoeheren Einschussenergien dominieren Praecompoundprozesse, und es wird eine Abnahme der Multiplizitaet beobachtet. (orig.)Additional details
