Abstract

The atomic charge state distributions of Er154158 ions produced in fusion reactions with S32 and S34 beams and Te126130 targets are used to deduce the average internal conversion probabilities of continuum γ transitions at high spin. A strong dependence is observed on both neutron number and spin. For each of the nuclei Er155158 a critical spin is observed at which a sudden enhancement of internal conversion occurs. This result alone implies either a sudden enhancement of M1 radiation, a sudden decrease of the average E2 transition energy, or some mixture of the two. In either case a major change in the underlying structure of the rotating body is implied. Previous continuum γ-ray spectroscopy measurements support the interpretation involving enhanced M1 radiation at very high spin.
