Abstract

Rotational photodetachment thresholds have been observed for SeH ^- ions in a magnetic field. Assignment and fitting of the thresholds determines the electron affinity and the rotational constants. The electron affinity of SeH is found to be 17845.17(20) cm^-1 and the rotational constants of SeH^- are B=7.7289(46) cm^-1 and D=3.33(9)*10^-4 cm^-1. The shape of the cross section near threshold and the appearance of oscillations in the cross section provide a test of the understanding of the effect of a magnetic field on the photodetachment cross section.
