Abstract

The anomalous intensity ratios observed in 209Bi were explained by Hüfnerl by a resonance mechanism, according to which the nucleus is excited into the 15/2+ (2.74 MeV) and 9/2+ (2.56 MeV) state. In this paper we report on the observation of nuclear γ rays following this excitation. Spectra were taken with a Ge-detector at the CERN muon channel. Four γ lines were identified in the prompt (1 2 3 4 Ge) spectrum as belonging to transitions in 209Bi. The energies Eμ and intensities Yexp of these lines are presented in table 1. They turn out to be shif-ted in energy by ΔEexp (table 1) compared to energies Ee as derived from Coulomb excitation2.
