ANGULAR-DISTRIBUTIONS OF AUGER TRANSITIONS OF N-2 TO DISSOCIATIVE FINAL-STATES

The angular distribution of the 360.2-eV Auger transition in N-2, whic h is attributed to an N-2(2+) (1) Pi(g) final state, is measured and c alculated. Calculations predict a sharper distribution than what is me asured. The angular distribution of the 363.5-eV Auger transition, att ributed to an N-2(2+) (1) Pi(u) final state is nearly isotropic in the laboratory frame. This is believed to be caused by metastable vibrati onal levels of the final state. The final state of the 358.7-eV transi tion was found to be nondissociative, and its angular distribution cou ld not be measured by our experimental technique. The peak in the N+ f ragment-ion spectrum at about 3.9 eV is assigned to the (3) Sigma(g)(- ) dissociative state of N-2(2+).
