Abstract
The beta(+)-electron capture decay of Kr-73, produced at the ISOLDE CERN fa cility, has been studied by beta-delayed proton and gamma emission. The est ablished decay scheme involves 15 up to now unreported gamma emitting level s in Br-73. The total proton branching ratio has been measured to be 0.0025 +/- 0.0003. From this work, a spin and parity 3/2(-) is assigned to the 73 Kr ground state, on the basis of the allowed beta branch to the Br-73 J(pi) = 1/2(-) ground state and the feeding of the 5/2(+) level located at 286 k eV in Br-73.
