A. Jungclaus et al. -- 6 pags., 5 figs., 2 tabs. -- Open Access funded by Creative Commons Atribution Licence 4.0, A new high-spin isomer in the neutron-rich nucleus Cd was populated in the projectile fission of a U beam at the Radioactive Isotope Beam Factory at RIKEN. A half-life of T=6.3(8) ms was measured for the new state which was tentatively assigned a spin/parity of (15). The experimental results are compared to shell model calculations performed using state-of-the-art realistic effective interactions and to the neighbouring nucleus Cd. In the present experiment no evidence was found for the decay of a 18 E6 spin-trap isomer, based on the complete alignment of the two-neutron and two-proton holes in the 0h and the 0g orbit, respectively, which is predicted to exist by the shell model., We thank the staff of the RIKEN Nishina Center accelerator complex for providing stable beams with high intensities to the experiment. We acknowledge the EUROBALL Owners Committee for the loan of germanium detectors and the PreSpec Collaboration for the readout electronics of the cluster detectors.

SHELL-MODEL CALCULATIONS ,DEFORMATION ,R-PROCESS ,NUCLEAR-STRUCTURE - Abstract
The beta decays Mn-68 -> Fe-68 -> Mn-69 -> Fe-69 and Mn-70 -> Fe-70 have been measured at the RIBF facility at RIKEN using the EURICA gamma spectrometer combined with an active stopper consisting of a stack of Si detectors. The nuclei were produced as fission fragments from a beam of U-238 at a bombarding energy of (345) MeV/nucleon impinging on a Be target and selected using the BigRIPS separator. Half-lives and beta-delayed neutron emission probabilities have been extracted for these decays, together with first experimental information on excited states populated in Fe-69,Fe-70. The data indicate a continuously increasing deformation for Fe isotopes up to A = 70. This is interpreted, as for Cr isotopes, in terms of the interplay between the quadrupole correlations of the nu 1d(5/2) and nu 0g(9/2) orbitals and the monopole component of the pi 0f(7/2)-nu 0f(5/2) interaction.
