Abstract

Using the wave functions yielded by the asymmetric rotor model with a decoupled odd nucléon with variable moment of inertia the absolute log ft values for some transitional odd-mass nuclei have been calculated. The dependence on the γ-deformation is important in a few cases. A great improvement is obtained in comparison with a pure spherical shell-model calculation.

Neutrino masses and right-handed current in the neutrinoless double beta decay 76Ge → 76Se + 2e-
1985, Physics Letters B
We calculated the nuclear matrix elements using the decoupling model extended to include also strong coupling. The closure approximation has been avoided and for the intermediate odd-odd nucleus $^{76} As$ a number of 70 states with 1⁺ have been generated and we summed up coherently their second order contribution. We found the neutrino mass to be limited by m_v,η=0^Maj ⩽ 4.2 and 9.3 eV and the admixture of a right-handed current bounded by η_{m_v=0}^Maj ⩽ 0.84 × 10⁻⁵ and 1.88 × 10⁻⁵, depending on the different experimental upper limits measured by direct counting methods. In the general case one finds m_v,η≠0^Maj ⩽7.2 eV and η_{m_v≠0}^Maj ⩽3.10 × 10⁻⁶ if Avignone's experiment is used.
