Photodetachment study of NH2− ions in the 22 pole trap — •Olga Lakhmanskaya1, Malcolm Simpson1, Simon Murauer1, Viatcheslav Kokoouline2, and Roland Wester1 — 1Universität Innsbruck, Innsbruck, Austria — 2University of Central Florida, Orlando, US
We present a near-threshold photodetachment spectrum of the amide anion NH2− performed in a cold (10 K) 22-pole ion trap. The spectrum shows steps in the relative cross section that are associated with the transitions between rotational levels of the vibrational ground states of NH2− (X1A1 electronic state) and NH2 (X2B1 electronic state). With this data we can significantly improve the determination of the electron affinity of amidogen NH2.
