Abstract

The energy of the first excited 2(+) state in Kr-96 was measured as 241 keV. The nucleus was produced in the fission of U-238 induced by a 954-MeV Xe-136 beam and prompt gamma rays were observed using the clover array CLARA in coincidence with fission products identified with the PRISMA spectrometer. The evolution of the quadrupole collectivity in the Kr isotopes with N >= 50 is discussed by comparison with that from the Rb to Mo isotones and with predictions of various theoretical calculations.
