DECAY PROPERTIES OF THE O-2(-PARITY ASSIGNMENTS IN KR-78() STATE AND SPIN)

The lifetime tau of the 0(2)(+) state in Kr-78 has been measured by me ans of the Doppler shift attenuation method in gases. From the value o f tau and the measured value of the K-internal conversion branching I- K(0(2)(+)-->)/I-K(0(2)(+)-->2(1)(+)) the value of the electric monopol e strength rho(2)(E0) of the 0(2)(+)-->0(1)(+) transition has been ded uced. Restriction or assignments for the spin parity of several levels in Kr-78, populated in the decay of Rb-78, have been deduced by measu ring K-internal conversion coefficients of the relevant transitions.
