Multipolarities of the Yrast and Statistical Cascades in the ReactionsNd150(Ne20,xnγ)

The total conversion coefficient, $\alpha$, of the $\gamma$-ray continuum has been determined as a function of $\gamma$-ray energy from 0.5 to 2.5 MeV. The results are consistent with a mixture of $E1\mathrm{}$ and $E2\mathrm{}$ for $E_{\gamma }>~1.0$ MeV, with a smooth increase of the $E1\mathrm{}$ fraction with $E_{\gamma }$ up to ∼1.5 MeV. At lower energy, in the upper half of the yrast region, $\alpha$ shows the expected dominance of $E2\mathrm{}$ radiation, but for the lower half an increasing $M1\mathrm{}$ contribution is found.
