✦ Synopsis

An infinite-order perturbation technique hss been used co obtain an elrpressfon for the T-matrix in ths vicinity of a zero-order bound state of the target-projectile compound system. All zero-order bound states can contribute resonance stqctures to the scattering cross section.

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

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

Elastic scattering of electrons by ozone is considered. Calculations are made at the static exchange level of approximation using the polyatomic R-matrix method. Several shape resonances are found below 20 eV scattering energy. Integral elastic scattering cross sections are evaluated and these are f
