Transition-Energy Correlations in the γ -Ray Continuum—A New Approach

A new method, which has been developed to isolate energy-correlated cascades from a background of uncorrelated events in the ..gamma..-ray continuum, has been applied to the /sup 16/O+/sup 64/Ni reaction at E (/sup 16/O) =80 MeV. In /sup 74/Se, the dominant reaction product, it gives 2J/h/sup 2/ app...

Zusammenfassung:	A new method, which has been developed to isolate energy-correlated cascades from a background of uncorrelated events in the ..gamma..-ray continuum, has been applied to the /sup 16/O+/sup 64/Ni reaction at E (/sup 16/O) =80 MeV. In /sup 74/Se, the dominant reaction product, it gives 2J/h/sup 2/ approx. = 53 +- 5 and 65 +- 6 MeV/sup -1/, respectively, for the rotationallike cascades below and above a phase transition observed at I approx. = 22 units. These data also indicate that only a small portion of the decay proceeds through rotationallike cascades.
