Neutron polarization with a polarized 3He spin filter
K. P. Coulter,T. E. Chupp,A. B. McDonald,C.D. Bowman,J. D. Bowman,J.J. Szymanski,V.W. Yuan,Gordon D. Cates,D.R. Benton,E. D. Earle +9 more
TL;DR: In this paper, the first use of a polarized 3 He spin filter to polarize epithermal neutrons was reported and the 3 He was polarized to 70% by spin exchange with optically pumped Rb vapor and had a cross sectional area of 0.65 cm 2 and a thickness of 3 × 10 20 atoms cm −2 of 3 He.
Journal ArticleDOI
Measurements on isovector giant resonances in pion charge exchange.
A. Erell,J. Alster,J. Lichtenstadt,Murray Moinester,J. D. Bowman,M. D. Cooper,F. Irom,H. S. Matis,Eli Piasetzky,Urs Sennhauser +9 more
TL;DR: The excitation energies and widths of the monopole and dipole are in good agreement with random-phase-approximation calculations and for the dipole they are also in agreement with other data.
Journal ArticleDOI
Test of Parity Conservation in p-p Scattering
James M. Potter,J. D. Bowman,C.F. Hwang,J.L. McKibben,R. E. Mischke,D. E. Nagle,P. Debrunner,Hans Frauenfelder,L. B. Sorensen +8 more
TL;DR: In this paper, the parity-nonconserving component in the nuclear cross section at 15 MeV was found to be (1/ifmmode\pm\else\textpm\fi{}4)
Journal ArticleDOI
Parity violation in proton-proton scattering at 221 MeV.
A. Berdoz,J. Birchall,J. B. Bland,J. D. Bowman,J.R. Campbell,G.H. Coombes,C. A. Davis,A. A. Green,P. W. Green,A. A. Hamian,R. L. Helmer,S. Kadantsev,Y. Kuznetsov,L. Lee,C. D. P. Levy,R. E. Mischke,N.

TL;DR: In this paper, a comprehensive analysis of the corrections required to arrive at the final result of Az = (0.84 ± 0.29(stat.) ± 0.17(syst.)) × 10 7, which greatly improves the experimental constraints on weak meson-nucleon coupling constants h pp and h pp, and also has implications for the interpretation of electron parity violation experiments.
Journal ArticleDOI
Sign correlations and parity nonconservation for neutron resonances in 232Th.
C. M. Frankle,J. D. Bowman,J. E. Bush,P. P. J. Delheij,C. R. Gould,David G. Haase,J. N. Knudson,G. E. Mitchell,Seppo Penttila,H. Postma,N. R. Roberson,S. J. Seestrom,J.J. Szymanski,S.H. Yoo,V.W. Yuan,Xiaofeng Zhu +15 more
TL;DR: The results suggest that the mechanism of parity violation in resonance reactions is more complicated than previously assumed and strong sign correlations are not a feature of the conventional statistical model of parity mixing between compound nuclear states.
