Constraints are reported on right-handed currents based on a precise comparison of the longitudinal β-polarizations PF and PGT in Fermi and Gamow-Teller transitions. Measurements with the matching isotopes 26mAl and 30P gave PF /PGT = 1.003 ± 0.004.

Constraints on right-handed currents are set by the precise comparison of the longitudinal polarizations PF and PGT in Fermi and Gamow-Teller beta+ decay. Measurements with a new fourfold Bhabha polarimeter gave PF/PGT=1.003+/-0.004 with use of the matching isotopes 26mAl and 30P. This ratio translates directly into a bound on the product of the mi...

The first excited ${0}^{+}$ state of $^{82}\mathrm{Kr}$ appears to have a noncollective nature, in contrast to the ${0}_{3}^{+}$ and other low-spin states in this nucleus. This is corroborated by a conversion-electron measurement of the ${0}_{2}^{+}$$\rightarrow${}${0}_{1}^{+}$ and the ${0}_{3}^{+}$$\rightarrow${}${0}_{1}^{+}$ transitions in $^{82}...

The first excited 0/sup +/ state of ⁸²Kr appears to have a noncollective nature, in contrast to the 0â/sup +/ and other low-spin states in this nucleus. This is corroborated by a conversion-electron measurement of the 0â/sup +/..-->..0â/sup +/ and the 0â/sup +/..-->..0â/sup +/ transitions in ⁸²Kr, following the decay of ⁸²Rb/sup g/. The...

... transitions that are newly identified herein and results are recorded in Table I respective initial and final states. The low-lying structure of 82 Kr (Fig. 1) relevant to this Letter is obtained by accumulating the extracted spectroscopic information and overlaps with the previously reported ones [27,33,34,36,37]. ...
... Indeed, the experimental investigation of the correlation coefficient Q ν (E e ) should be performed for polarized neutrons and longitudinally polarized decay electrons. This is unlike the experiments i) on the neutron beta decay for polarized neutrons and transversally polarized electrons [17,24,75,76] and ii) on the nuclear beta decays for unpolarized nuclei and longitudinally polarized decay positrons [12,[77][78][79]. Moreover, the dependence of the correlation structure on the antineutrino 3-momentum demands a simultaneous detection of decay electron and protons, i.e. electron-proton pairs, similar to the measurements of the antineutrino asymmetry [81][82][83]. ...
