Lifetime measurements have been made in the neutron-deficient nucleus 109Te using the coincident recoil
distance Doppler-shift method. The experimental B(E2) values have been compared with state-of-the-art shellmodel
calculations using the monopole-corrected realistic charge-dependent Bonn nucleon-nucleon potential.
Lifetimes in the νh11/2 band are consistent with an interpretation based on the deformation driving properties
of a single valence neutron outside of the even-even tellurium core and highlight the unexpected presence
of collective behavior as the N = 50 shell closure is approached. Lifetime measurements for the low-lying
positive-parity states also appear to correlate well with shell-model calculations. In addition, a comparison with
the proton-unbound nucleus 109I suggests that the presence of a single decoupled valence proton affects the total
measured B(E2) strengths in a manner that is not currently well understood.

Towards an Experimental Determination of the Transition Strength Between the Ground States of 20F and 20Ne
Kirsebom, Oliver S.; Cederkäll, Joakim; Jenkins, David G.; Joshi, Pankaj; Julin, Rauno; Kankainen, Anu; Kibédi, Tibor; Tengblad, Olof; Trzaska, Wladyslaw (Physical Society of Japan, 2017)Electron capture on 20Ne is thought to play a crucial role in the final evolution of electron-degenerate ONe stellar cores. Recent calculations suggest that the capture process is dominated by the second-forbidden transition ... -
Muon-electron lepton-flavor-violating transitions : Shell-model calculations of transitions in 27Al
Kostensalo, Joel; Suhonen, Jouni; Civitarese, O. (American Physical Society, 2018)In this paper we present the results of large-scale shell-model calculations of muon-to-electron lepton-flavorviolating transitions for the case of the target nucleus 27Al. We extend the previous shell-model calculations, done ... -
