The energy of the first excited 2{sup +} state in {sup 96}Kr was measured as 241 keV. The nucleus was produced in the fission of {sup 238}U induced by a 954-MeV {sup 136}Xe 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.
