The Gamow-Teller transitions in the96Pd→96Rh decay

Using the40Ca(4.2 MeV/u) +60Ni reaction and on-line mass separation, the decay properties of 46 96 Pd50 were reinvestigated. From a comparison of experimental and theoreticalβ+/(EC +β+) probability ratios, theQEC value was deduced to be 3,450 ± 150 keV. The strength was determined for four 0+→1+ Gamow-Teller beta transitions and found to be quenched as compared to predictions of the single-particle shell model. For96Pd and94Ru the sources of this quenching are discussed.
