Isotope shift in the electron affinity of chlorine
Uldis Berzinsh, Morgan Gustafsson, Dag Hanstorp +3
The specific mass shift in the electron affinity between ^{35}Cl and ^{37}Cl has been determined by tunable laser photodetachment spectroscopy to be -0.51(14) GHz. The isotope shif…
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^-…
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…
