Abstract
Coincidence and gamma-gamma directional correlation measurements are made for the 10 cascades of s2Kr: 1648-777, 1008-1044, 1317-777, 619-1475, 555-1317,555-619,828-1044,828-(1044)-777,698-777, and 619-698 keV, of which the cascade 1008-1044 keV has been attempted for the first time. The results permit a unique spin assignment of 5 for the 2829 ke V level from the directional correlation of the 1008-1044 keV cascade and a spin of 3 to the level at 2425 keV from that of the 1648-777 keV cascade. Multipole character and admixture are determined for the transitions 1648, 1475, 1044, 1008, 555, 828, 698, 619, and 1317 keV. Computed E2 partial half-lives for the last two transitions are compared with the predictions of the single-particle estimate and the nonaxial rotor model.
