Photodetachment study of He^- quartet resonances below the He(n=3) thresholds
Andreas E. Klinkmueller, G. Haeffler, D. Hanstorp +3
The photodetachment cross section of He^- has been measured in the photon energy range 2.9 eV to 3.3 eV in order to investigate doubly excited states. Measurements were made channe…
Two electron dynamics in photodetachment
D. Hanstorp, G. Haeffler, A. E. Klinkmueller +4
We present the results of experimental studies of photon-negative ion interactions involving the dynamics of two electrons. Resonances associated with doubly excited states of Li^-…
Electron affinity of Li: A state-selective measurement
Gunnar Haeffler, Dag Hanstorp, Igor Kiyan +3
We have investigated the threshold of photodetachment of Li^- leading to the formation of the residual Li atom in the state. The excited residual atom was selectively phot…
The electron affinity of tellurium
Gunnar Haeffler, Andreas E. Klinkmueller, Jonas Rangell +2
The electron affinity of tellurium has been determined to 1.970 876(7) eV. The threshold for photodetachment of Te^-(^{2} P_{3/2}) forming neutral Te in the ground state was invest…
Photodetachment study of the 1s3s4s ^4S resonance in He^-
Andreas E. Klinkmueller, Gunnar Haeffler, Dag Hanstorp +5
A Feshbach resonance associated with the 1s3s4s ^{4}S state of He^{-} has been observed in the He(1s2s ^{3}S) + e^- (εs) partial photodetachment cross section. The residual He(1s2s…
