A study to determine the optimum magnet system for a polarized atomic hydrogen jet target is described. The design uses an atomic beam source with Ne–Fe–B permanent sextupole magnets to focus the beam and high frequency hyperfine transitions to p

The longitudinal polarization of positrons emitted along and opposite to the nuclear spin direction has been measured in the decay of polarized N-12. The results are consistent with the Standard Model prediction. In manifest left-right symmetric mode

We report on the status of the measurements of the longitudinal polarization of positrons emitted by polarized 107In and 12N nuclei. Present results yield a lower limit of 306 GeV/c2 (90 % CL) for the mass of a possible W gauge boson with predominant

Measurements of the Polarization-Asymmetry Correlation (PAC) in nuclear beta decay require samples of high polarization and activity which are well coupled to an efficient polarimeter. We have developed a system to accomplish this and used it in prel

We measured ${}^{36}$Ar$(p\ensuremath{\rightarrow}{,p}_{0})$ cross sections and analyzing powers for ${E}_{p}$ between 3.22 and 5.98 MeV, and used these data to deduce spin, parity, and widths of 17 levels in ${}^{37}$K. Our results, combined with ex

We studied parity mixing of the ${0}_{2}^{+}$,${0}_{1}^{\mathrm{\ensuremath{-}}}$; I=1 doublet in $^{14}\mathrm{N}$ (${\mathit{E}}_{\mathit{x}}$\ensuremath{\sim}8.6 MeV) to probe the isoscalar component of the parity nonconserving (PNC) nucleon-nucle

In view of the recent improvements in the evaluation of the correction terms in superallowed Fermi Ft-values, we revisit the limits on scalar couplings deduced from their constancy as a function of energy release. Taking into account the presence of

The asymmetry parameter for the superallowed, mixed Fermi-Gamow-Teller s-decay of polarized 35 Ar to the mirror nucleus 35 Cl ground state has been measured. The result, A gs = 0.427 ± 0.023, is in good agreement with the Standard Model expectation
