TL;DR: It is suggested that this coupling scheme replaces normal superfluidity in the ground and low-lying excited states of the heaviest N = Z nuclei, and has a considerable impact on the nuclear level structure and possibly influence the dynamics of rapid proton capture in stellar nucleosynthesis.
Journal ArticleDOI
128Cs as the best example revealing chiral symmetry breaking.

TL;DR: The results of the Doppler-shift attenuation method lifetime measurements in partner bands of 128Cs and 132La show that 128Cs is the best known example revealing the chiral symmetry breaking phenomenon.

TL;DR: In this article, the lifetime of the excited states belonging to the chiral partner bands built on the π h 11/2 ⊗ ν h 11 / 2 − 1 configuration in 126Cs have been measured using the DSA technique.
Journal ArticleDOI
The single-closed-shell nucleides 14462Sm82 and 14664Gd82
TL;DR: In this paper, the existence of excited states with the spin sequence 6 + → 4 + → 2 + → 0 + is established in both of them, similarly to all the other known N = 82, even-Z isotones.
