TL;DR: The nuclear structure of 225Th has been studied using the reaction 226Ra(α, 5n) 225Th at a beam energy of 50 MeV as mentioned in this paper, where in-beam γ-branching ratios have been measured and an average value of |D0/Q0| = (0.51±0.06)×10−3fm−1 has been deduced.

Abstract: High-spin states in Kr-76(36)40 have been populated in the Ca-40(Ca-40,4p)Kr-76 fusion-evaporation reaction at abeam energy of 165 MeV and studied using the Gammasphere and Microball multidetector arrays. The ground-state band and two signature-split negative parity bands of Kr-76 have been extended to similar to 30 (h) over bar. Lifetime measurements. using the Doppler-shift attenuation method show that the transition quadrupole moment of these three bands decrease as they approach their maximum-spin states. Two signatures of a new rotational structure with remarkably rigid rotational behavior have been identified. The high-spin properties of these rotational bands are analyzed within the framework of configuration-dependent cranked Nilsson-Strutinsky calculations. (Less)

TL;DR: In this paper, high-spin states in the nucleus of the nucleus {sup 183}Tl have been studied using the recoil decay tagging and recoil tagging techniques, which have enabled new structures to be identified which are believed to be based on prolate f{sub 7/2}, h{sub 9/2], and oblate hµsub 3/2} configurations.

TL;DR: In this paper, the authors investigated whether isospin mixing can be determined in a model-independent way from the relative strength of E1 transitions in mirror nuclei and obtained a lifetime for the relevant 7/2-state in S31 using the Doppler-shift attenuation method.

TL;DR: In this paper, out-of-beam measurements of alpha-gamma and alpha-e coincidences were performed with the aid of a rotating target mechanism, enabling a limited level scheme of the low-spin states in Th223 to be constructed, along with tentative J-pi assignments and alpha hindrance factors.
