The Structure of Triply Excited, Negative-Ion Resonances in the Autoionizing Region of Helium

Trantham, K W; Rau, A R P; Buckman, Stephen

Description

The formation and decay of the two lowest-lying, triply excited He- resonances in the autoionizing region of the helium spectrum (57-60 eV) have been studied by measuring electron-impact excitation functions for the n = 2 singly excited states of helium as a function of electron scattering angle. These results offer unambiguous confirmation of the classification of these states as He- 2s 2p22P and 2s2p22D, respectively. Furthermore, the observation of the relative strengths of the decay of...[Show more]
