DIFFERENTIAL CROSS-SECTIONS AND ANGULAR-CORRELATION FUNCTIONS IN ELECTRON-HYDROGEN SCATTERING FOR ENERGIES BETWEEN N=3 AND N=4 THRESHOLDS

Differential cross sections and electron-photon angular correlation fu nctions for electron impact excitation of hydrogen atoms in the energy range between the n = 3 and n = 4 thresholds were calculated using th e algebraic variational method. The cross sections and correlation fun ctions show complicated and irregular structures associated with overl apping resonances in different partial waves. The availability of thes e quantities may help interested experimentalists to determine resonan ce positions, and also may furnish an important test of the adequacy o f the computations.
