Lineshape response of plastic scintillator to pair production of 4.44 MeV gamma's

Melisa Ozen, John A. Behr, Michelle Khoo +3

We measure the distribution of energy deposited in a 40x88 mm plastic scintillator by e+ e- pair production of 4.44 MeV gamma-rays. We observe the double-escape peak of 3.42 MeV fr…

$A_{β} [E_{β}]$ 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…
