in K decay: new physics with opposite helicity
Melissa Anholm, J. A. Behr, D. G. Melconian +5
By extending our analysis and simulations of our K -decay data set to allow the asymmetry with respect to nuclear spin to vary with energy , we have gained s…
Isotope Shifts in the 7s8s Transition of Francium: Measurements and Comparison to \textit{ab initio} Theory
M. R. Kalita, J. A. Behr, A. Gorelov +10
We observe the electric-dipole forbidden transition in the francium isotopes Fr and Fr using a two-photon excitation scheme. We collect the at…
Precision measurement of the -asymmetry in spin-polarized decay
B. Fenker, A. Gorelov, D. Melconian +13
Using TRIUMF's neutral atom trap, TRINAT, for nuclear decay, we have measured the asymmetry with respect to the initial nuclear spin in to be $A_β=-0.5707…
Precision measurement of the nuclear polarization in laser-cooled, optically pumped
Benjamin Fenker, John A. Behr, Dan Melconian +18
We report a measurement of the nuclear polarization of laser-cooled, optically-pumped atoms which will allow us to precisely measure angular correlation parameter…
