Lifetimes of excited states in Rh-
J. Karls, J. Grumer, S. Schiffmann +13
The radiative decay of excited states of the negative ion of rhodium, Rh, has been investigated experimentally and theoretically. The experiments were conducted at the Double E…
Observation of an electric quadrupole transition in a negative ion: Experiment and Theory
C. W. Walter, S. E. Spielman, R. Ponce +4
The first direct experimental observation of an electric quadrupole (2) transition between bound states of an atomic negative ion has been made. The transition was obse…
Predicting quasibound states of negative ions
M. S. Safronova, C. Cheung, M. G. Kozlov +3
We demonstrated the accurate prediction of a quasibound spectrum of a negative ion using a novel high-precision theoretical approach. We used La as a test case due to a recent…
Photodetachment Spectroscopy of Quasibound States of the Negative Ion of Lanthanum
C. W. Walter, N. D. Gibson, N. B. Lyman +1
The negative ion of lanthanum, La, has one of the richest bound state spectra observed for an atomic negative ion and has been proposed as a promising candidate for laser-cooli…
LSST Target of Opportunity proposal for locating a core collapse supernova in our galaxy triggered by a neutrino supernova alert
Christopher W. Walter, Daniel M. Scolnic, Anže Slosar
A few times a century, a core collapse supernova (CCSN) occurs in our galaxy. When such galactic CCSNe happen, over 99\% of its gravitational binding energy is released in the form…
Threshold photodetachment in a repulsive potential
Anton O. Lindahl, Johan Rohlén, Hannes Hultgren +4
We report on the first experimental observation of a new threshold behavior observed in the 5g partial channel in photodetachment of K-. It arises from the repulsive polarization i…
