[en] Negative-parity excitations in the 2.5 MeV region in 112Cd have been investigated with the (n,n'γ reaction. Several of these states exhibit enhanced B(E2) values for decay to the 31- octupole state, indicative of quadrupole-octupole coupled (2+x3-) structures. The B(E1) values observed are typically in the range of 1-5x10-4 W.u., irrespective of the final state. (author)

[en] I have performed a two-state mixing analysis between so-called rotational intruder , and yrast , states in 112Cd, fitting E2 transition matrix elements to obtain mixing amplitudes and matrix elements connecting basis states. Mixing is found to be small for both and states. Of two possible solutions, one provides a mixing amplitude of 0.251– identical to the one derived years ago from 2n transfer data.

[en] The EO and E2 transitions from the first excited O+ state in 112Cd were observed from an internal conversion electron study. Values for the ratio X(EO/E2) and for the nuclear matrix element ρ(EO) were obtained and are compared with theoretical values for a 2p2hQV model$

[en] The properties of negative-parity states in the 2.5 MeV region in 112Cd have been investigated with the (n,n'γ) reaction. For many of these levels, lifetimes have been measured, and B(E1) and B(E2) values for their decays have been determined. Several transitions exhibit enhanced B(E2) values for decay to the 31- octupole state, indicative of quadrupole-octupole coupled (2+circle-times 3-) states. The B(E1) values observed are typically in the range of 1 - 5x10-4 Weisskopf units (W.u.), irrespective of the final state. copyright 1999 The American Physical Society

[en] Existing (e, 2e) angular distribution measurements and (e, 2e) energy spectra in atomic cadmium are reviewed and a major difference in the analyses of the two data sets is highlighted. It is shown that an autoionizing level, previously postulated to explain the angular distribution data, does not exist, and is an artefact of the simplifying assumptions used in the original analysis. A new calculation is presented which unifies the interpretation of the measured angular distributions and the energy spectra. (author)
