High-spin states of the neutron deficient (100)pd nucleus have been investi
gated via the Cr-50(Ni-58, 4p alpha) and Zn-70(S-36,6n) heavy-ion induced r
eactions. For the detection of evaporated particles and gamma rays the NORD
BALL array equipped with ancillary detectors and the EUROGAM II detector sy
stem were utilized. By the use of in-beam spectroscopic methods 89 transiti
ons belonging to (100)pd have been observed, 49 of which were identified fo
r the first time. The level scheme has been extended up to E-X approximate
to 16 MeV excitation energy and I approximate to 25h. The experimental resu
lts were compared with the predictions of cranked shell model calculations.
Maximal spin alignments were found in the (pig(9/2))(12+)(-4) (vd(5/2),g(7
/2)(3)h(11/2))(13-) and (pig(9/2)(-3)p(1/2))(11-)(vd(5/2)g(7/2)(3)h(11/2))(
13-) configurations. Possible existence of octupole correlations is discuss
ed on the basis of 6 (E 1)lB(E2) values deduced for the decays of high-spin
levels in the yrast negative-parity band. (C) 2001 Elsevier Science B.V. A
