Seo, E I Sharapov, T B Smith, W M. Snow, W S Wilburn, V Yuan
Abstract: The NPDGamma collaboration reports results from the first phase of a measurement of the parity violating up-down asymmetry A_gamma with respect to the neutron spin direction of gamma-rays emitted in the reaction n + p -> d + gamma using the capture ...

4. A New Cold Neutron Imaging Instrument at NIST
Published: 7/6/2015
Authors: Daniel S Hussey, Christoph Wilhelm Brocker, David L Jacobson, Thomas R Gentile, Wangchun Chen, Elias M Baltic, DV Baxter, J. Doskow, Muhammad Arif
Abstract: The NIST neutron imaging program will build a new imaging instrument in the NCNR guide hall at the end of the neutron guide NG-6, beginning operation in summer of 2014. The NG-6 guide has a spectrum that is strongly peaked at a neutron wavelength of ...

5. A New Method for Precision Cold Neutron Polarimetry Using a ^u3^He Spin Filter
Published: 1/1/2005
Authors: Fred Eberhardt Wietfeldt, Thomas R Gentile

6. A Wide Angle Neutron Spin Filter System Using Polarized 3He
Published: 10/16/2010
Authors: Changbo Fu, Thomas R Gentile, Wangchun Chen, Ross W. Erwin, Shannon Watson, Collin L. Broholm, Jose A. Rodriguez, Julia K Scherschligt, G L Jones
Abstract: Polarized 3He neutron spin filters can operate over a wide neutron energy range and provide a large angular acceptance. A compact 3He neutron spin filter system has been developed for the Multi Axis Crystal Spectrometer at the NIST Center ...

7. A gamma and X-ray dector for cryogenic, high magnetic field applications
Published: 7/13/2012
Authors: Thomas R Gentile, R L Cooper, R. Alarcon, M J Bales, E J Beise, H Breuer, J. Byrne, T E. Chupp, Kevin J Coakley, Maynard S Dewey, Changbo Fu, Hans P Mumm, Jeffrey S Nico, Brian O'Neill, K. Pulliam, Alan K Thompson, F E. Wietfeldt
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 ...
