Full One-Loop Radiative Corrections to the Asymmetry Parameter of Polarised Neutron Beta Decay
We present a calculation of full one-loop radiative corrections, including the constant term, to the asymmetry parameter of polarised neutron beta decay. This gives the radiative correction to the axial coupling constant gA extracted from the beta asymmetry so that it ties to gA that appears in neutron decay lifetime in a consistent renormalisation scheme. We find that the ratio of axial-vector...

Masses of the radioactive isotopes Ga, Zn and Cu have been measured at the JYFLTRAP facility with a relative precision of better than 1.8× 10. A QEC value of (9181.07 ± 0.54) keV for the superallowed decay of Ga is obtained from the measured cyclotron frequency ratios of Ga—Zn, Ga—Ni and Zn—Ni ions. The resulting Ft-value supports the validity of the conserved vector current hypothesis (CVC). T...

متن کاملOverconstrained estimates of neutrinoless double beta decay within the QRPA
Estimates of nuclear matrix elements for neutrinoless double beta decay (0ν2β) based on the quasiparticle random phase approximations (QRPA) are affected by theoretical uncertainties, which can be substantially reduced by fixing the unknown strength parameter gpp of the residual particle-particle interaction through one experimental constraint — most notably through the twoneutrino double beta ...
متن کاملBeta-gamma directional correlation measurements in the decay of gallium-72
The beta-gamma directional correlation involving the first forbidden,2.52 Mev, <#-group in coincidence with the 1.465 Mev 72 S' transition, in the 14-hours decay of Ga, has been measured as a function of energy of the beta-particles . The correlation coefficient A^ was determined at five (Z energies ranging from 1.839 to 2.248 Mev as given below :
