Journal ArticleDOI
Beta-decay asymmetry of the neutron and gA/gV.
TL;DR: In this article, the free neutron decay asymmetry was measured by using a beam of polarized neutrons and a long solenoidal spectrometer with 4π solid angle for electron detection.
Journal ArticleDOI
Evidence against a 17 keV neutrino from S 35 beta decay
J. L. Mortara,I. Ahmad,Kevin P. Coulter,S. J. Freedman,B. K. Fujikawa,John P. Greene,J. P. Schiffer,W. H. Trzaska,A.R. Zeuli +8 more
TL;DR: The authors' sensitivity to neutrino mass is verified by measurements with a mixed source of [sup 35]S and [sup 14]C, which artificially produces a distortion in the beta spectrum similar to that expected from the massive neutrinos.
Journal ArticleDOI
Measurement of the Differential Cross Section for the reaction 2H(γ,p)n at High Photon Energies and θc.m.=90°
Jim Napolitano,Jim Napolitano,S. J. Freedman,D. F. Geesaman,Ronald Gilman,M.C. Green,R. J. Holt,H. E. Jackson,R.S. Kowalczyk,C. Marchand,C. Marchand,J. E. Nelson,B. Zeidman,Douglas H Beck,G. Boyd,D. Collins,B. W. Filippone,J. Jourdan,R. D. McKeown,R. G. Milner,D. H. Potterveld,D. H. Potterveld,R. C. Walker,C. E. Woodward,R. E. Segel,T. Y. Tung,P. E. Bosted,E. R. Kinney,E. R. Kinney,Z. E. Meziani,R. C. Minehart +30 more
TL;DR: In this paper, the authors measured the differential cross section for two-body deuteron photodisintegration at θc.m.=90° and for photon energies between 0.8 and 1.6 GeV.
Journal ArticleDOI
Search for a light scalar boson emitted in nuclear decay
TL;DR: The possibility that a scalar boson is sometimes emitted in the decay of /sup 4/He (20.1 MeV, 0/sup +/) is examined experimentally.
Journal ArticleDOI
Two-body disintegration of the deuteron with 0.8-1.8 GeV photons.

TL;DR: The differential cross section for the reaction 2H(γ,p)n has been measured at several center-of-mass angles and the energy dependence of the cross sections is consistent with predictions of scaling using counting rules for constituent quarks.
