$A_{β} [E_{β}]$ in $^{37}$ K decay: new physics with opposite $β$ helicity

Melissa Anholm, J. A. Behr, D. G. Melconian +5

By extending our analysis and simulations of our $^{37}$ K $β$ -decay data set to allow the $β$ asymmetry with respect to nuclear spin to vary with $β$ energy $E_{β}$ , we have gained s…

Precision measurement of the $β$ -asymmetry in spin-polarized $^{37} K$ decay

B. Fenker, A. Gorelov, D. Melconian +13

Using TRIUMF's neutral atom trap, TRINAT, for nuclear $β$ decay, we have measured the $β$ asymmetry with respect to the initial nuclear spin in $^{37} K$ to be $A_β=-0.5707…

Precision measurement of the nuclear polarization in laser-cooled, optically pumped $^{37} K$

Benjamin Fenker, John A. Behr, Dan Melconian +18

We report a measurement of the nuclear polarization of laser-cooled, optically-pumped $^{37} K$ atoms which will allow us to precisely measure angular correlation parameter…
