PairingModel Calculation of Nuclear Matrix Elements in the Decay of ^{74}As
Abstract
The matrix elements C_{A}σ.r, C_{A}r, C_{V}iσ×r, and C_{A}B_{ij} are calculated for ^{74}As, using the pairing model. C_{V}iα is determined from the conserved vector current theory, and C_{A}iγ_{5} from βγ angular correlation data. The ratio of the (B_{ij})^{1}(B_{ij})^{2} for the β transitions to the ground state and first excited state, respectively, of ^{74}Ge is calculated from these matrix elements and the β intensities. This ratio is also calculated solely from the model and compared with the above ratio to check the internal consistency of the method. The results show that better agreement is obtained if the effect of phononquasiparticle coupling is included.
