QUADRATIC BEHAVIOR OF Ft VALUES OF SUPERALLOWED FERMI BETA DECAYS

In the present work, quadratic behavior of Ft values of the superalloved 0 0 Fermi beta transitions have been investigated by on the eleven well known superallowed Fermi Beta decays; the parent nuclei are 10C, 14O, 26Al, 34Cl, 38K, 42Sc, 46V, 50Mn, 54Co, 62Ga, 74Rb. Broken isospin symmetry of shell model Hamiltonian has been restored by Pyatov method. Within the Random Phase Approximation (RPA), calculations have been performed considering without and with pairing interactions.
