Abstract

A new method, which has been developed to isolate energy-correlated cascades from a background of uncorrelated events in the $γ$ -ray continuum, has been applied to the ${}^{16}O$ + ${}^{64}{Ni}$ reaction at $E ({}^{16}O) = 80$ MeV. In ${}^{74}{Se}$ , the dominant reaction product, it gives $\frac{2 I}{ℏ^{2}} ≃ 53 \pm 5 and 65 \pm 6$ ${MeV}^{- 1}$ , 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.
