Negative ion resonance measurements in the autoionising region of helium measured across the complete angular scattering range (0°-180°)

Abstract

Excitation function measurements for the decay of the 2s 2 2p 2 P and 2s2p 2 2 D triply excited negative ion resonances in helium to singly excited n=2 states have been measured. These excitation functions have been determined across the complete angular range (0-180°) using a magnetic angle changer (MAC) with a soft-iron core. The convergent close-coupling… (More)
