Conversion electron study of Cd-110 following β decay of In-110
Abstract
The nucleus 110Cd exhibits shape coexistence with deformed 2 p - 4 h proton excitations forming an intruder band coexisting with less-deformed normal states. The normal states were long thought to be multi-phonon states built on a spherical shape, but recent work has suggested that the underlying shape is that of a deformed γ-soft rotor, rather than a spherical vibrator. An ideal probe of mixing of different nuclear shapes is a measurement of E 0 strengths. The β-decay of 110In was studied at TRIUMF using the 8 π spectrometer and its auxiliary detectors including 5 Si(Li) detectors. The decay scheme of excited states in 110Cd was constructed using the e- - γ -coincidences. The subshell ratios and conversion coefficients α of observed conversion electrons were extracted, and used to determine new E 0 transition branches. Using information on the level lifetimes, the ρ2 (E 0) values for the new transitions have been determined.
