Abstract

The time-integral angular distribution was measured as a function of an external magnetic field for γ-rays from the 398-keV 9/2 state of69Ge populated by bombarding a Zn single crystal with a natural α-beam from a cyclotron. Clear resonances of dispersion as well as Lorentz types having a natural width (τ=4 μs) were observed at Bres=9.14 kG corresponding to the first level-crossing resonance of the 9/2 state due to the combined collinear magnetic and electric interactions. The effects of non-collinearity were also demonstrated, and compared with theory.
