Abstract
Odd-odd Cs nuclei have been produced in the Pb and U fusion-fission reactions and their rays studied with the Euroball array. The high-spin level scheme was built up to 4.7 MeV excitation energy and spin from the triple -ray coincidence data. The configurations of the three structures observed above 2 MeV excitation energy are first discussed by analogy with the proton excitations identified in the semimagic Cs nucleus, which involve the three high- orbits lying above the gap, , , and . This is confirmed by the results of shell-model calculations performed in this work.
