✦ Synopsis

The Blair-Austern (1) expression for the cross section for inelastic scattering via collective excitation, under strong absorption conditions, is rederived using the W.K.B. approximation. It is then shown that application of a small number of approximations transforms the Blair-Austern formula into a very simple, analytical expression, suitable for comparison with experiment without resorting to lengthy computer calculations. The Blair Phase Rule is obtained from this expression for all angles and the double phase rule is shown to be valid only for large angles. The resulting expression is compared to experimental cross sections to illustrate the validity of the approximations. Satisfactory agreement is obtained.

Closed-form expressions are derived for the differential cross section for inelastic scattering via mutual and double collective excitations and under strong absorption conditions. The expressions result in the generalized "Blair phase Rules." The predictions are compared with experimental data and
