The experimental and theoretical evidence for intrinsic reflection-asymmetric shapes in
nuclei is reviewed. The theoretical methods discussed cover a wide spectrum, from mean …

Background: The phenomenon of reflection-asymmetric nuclear shapes is relevant to
nuclear stability, nuclear spectroscopy, nuclear decays and fission, and the search for new …

A= 140–148 even-even barium nuclei produced in the spontaneous fission of 248Cm were
studied using the EUROGAM2 array. Spins and parities of excited levels have been firmly …

The high spin level structures of Ru 100 have been studied through discrete-line γ-ray
spectroscopy. This study reveals the existence of seven interleaved E 1 transitions between …

Multinucleon transfer reactions have been used, for the first time, to populate high-spin
bands of alternating parity states in 2 1 8, 2 2 0, 2 2 2 Rn and 2 2 2, 2 2 4, 2 2 6 Ra. The …

Independent yields of 139 individual secondary (appearing after neutron evaporation)
fragment pairs of five different charge splits (ZL/ZH= 46/52, 44/54, 42/56, 40/58, and 38/60) …

The possibility of the existence of octupole deformation in Pm 151 has caused interest for
about thirty years. In this paper, the observed low-lying positive-and negative-parity …

The nuclei 143,145,147 Ba produced in the spontaneous fission of 248Cm have been
studied using the EUROGAM phase II array. The parities and multipolarities of γ rays in …

Level structures in the neutron-rich Ba 144 nucleus have been reinvestigated by measuring
prompt γ rays in the spontaneous fission of Cf 252. The previous s=+ 1 octupole band …

Several new high-spin states are observed in the prompt γ-rays emitted from the neutron-
rich, odd-Z 1 4 5, 1 4 7 La fragments produced in the spontaneous fission of 252 Cf …
