Investigation of the excitation of 186Re from (n,γ) reactions

Description

From the reaction 185Re(n,γ)186Re, prompt and retarded γ-γ coincidences in 186Re were investigated with Ge(Li) detectors. Two new isomers were found: the state at 99.4 keV with T(1/2) = 27 ns and the state at 330 keV with T(1/2) = 17.4 ns. The evaluation of the coincidence data led to the discovery or extension of 10 rotation bands with band heads below 700 keV. The level scheme is discussed in detail. (orig./LH)

Es wurden zwei neue Isomere gefunden: der Zustand bei 99,4 keV mit T(1/2) = 27 ns und der Zustand bei 330 keV mit T(1/2) = 17,4 ns. Die Auswertung der Koinzidenzdaten fuehrte zur Entdeckung bzw. Erweiterung von 10 Rotationsbanden mit Bandenkoepfen unter 700 keV. Das Niveauschema wird im Detail diskutiert. (orig./WL)
