Gamma-Ray Decaying States at High Excitation in sup 20 /Ne

摘要

A search has been made for high-lying states in sup 20 /Ne which decay by gamma -ray emission. The states were populated via the sup 12 C( sup 12 C, alpha ) sup 20 /Ne reaction at a beam energy of 37.1 MeV. A technique which allowed the measurement of gamma -ray emission probabilities down to less than 1% was employed. In addition to previously known gamma -ray emitting states, at 11.89, 12.01, 12.10, 12.17 and 12.38 MeV were found to have observable gamma -ray decay modes. (ERA citation 12:027829)
