Two neutrino double beta decay within the ξ-approximation

Abstract We examine the contributions of odd-parity nuclear operators to the two-neutrino double beta decay 0+ → 0+ amplitude, which come from the P-wave Coulomb corrections to the electron wave functions and the recoil corrections to the nuclear currents. Although they are formally of higher order...

description Abstract We examine the contributions of odd-parity nuclear operators to the two-neutrino double beta decay 0+ → 0+ amplitude, which come from the P-wave Coulomb corrections to the electron wave functions and the recoil corrections to the nuclear currents. Although they are formally of higher order in αZ/2 or v/c of the nucleon than the usual Fermi and Gamow-Teller matrix elements, explicit calculations performed within the QRPA show that they are significant when compared with the experimental data.
