Abstract: As part of an experiment to measure the spectrum of photons emitted in beta-decay of the free neu- tron, we developed and operated a detector consisting of 12 bismuth germanate (BGO) crystals coupled to avalanche photodiodes (APDs). The detector wa ...

Abstract: The neutron typically beta decays into a proton, electron, and antineutrino. In some decays, it can be accompanied by a high energy photon. We recently performed the rst observation of the radiative beta decay branch for the free neutron with phot ...

10. Comment on "Enhanced polarization and mechanisms in optically pumped hyperpolarized ^u3^He in the presence of ^u4^He"
Published: 7/24/2013
Authors: Thomas R Gentile, M E Hayden, P.J. Nacher, A K. Petukhov, B Saam, T G Walker
Abstract: H.H. Chen et al [1] claim that adding 4He to spin-exchange optical pumping (SEOP) cells confines 3He atoms to a diffusion-limited region, which effectively reduces the wall relaxation factor X. Here X is a phenomenological parameter used to charact ...
