IN-BEAM SPECTROSCOPY AND SHELL-MODEL STRUCTURE OF THE NEUTRON-DEFICIENT IN-103 AND CD-100,CD-102

The gamma-decay of the neutron deficient nuclei In-103 and Cd-100.102 has been studied following the reactions Ni-58 + Cr-50 and Ni-58 + Ti- 46.48 at 250 MeV and 230 MeV bombarding energy of the Ni-58 beam, resp ectively. Evaporation neutrons and charged particles were measured in coincidence with prompt and delayed gamma-rays with the multidetector array OSIRIS. To investigate the decay of the I-pi = 8(+) isomers of C d-100.102 a recoil catcher setup inside OSIRIS was used. Six new gamma -ray transitions of Cd-100 and four of Cd-102 with intensities of 1-10 % of the main gamma-ray cascades were found. Two new states of Cd-100 were established and firm spin-parity assignments were made to all sta tes below the isomer. These new states were identified as the 4(+) and the 6(+) members of the proton pi g(9/2)(-2) multiplet. The experimen tal states of In-103 and of Cd-100.102 are compared to shell model pre dictions in the pi(p(1/2), g(9/2)) v(d(5/2), g(7/2), s(1/2), d(3/2), h (11/2)) configuration space.
