Isomers and Seniority in the Trans-Pb Nuclei
نویسندگان
چکیده
Low-energy excited states of 210Ra and 208Ra were investigated at the Wright Nuclear Structure Laboratory of Yale University. Fusion evaporation recoils were selected using the gas-filled spectrometer, SASSYER. Delayed γ -rays, following isomeric decays, were detected at the focal plane of SASSYER with a small array of HPGe detectors. Transitions following the proposed J = 8+ isomers were observed, and the half-lives measured. The experiments are discussed and results compared to expectations from the seniority scheme.

New shell model Hamiltonians are derived for the T=1 part of the residual interaction in the f5/2 p3/2 p1/2 g9/2 model space based on the analysis and fit of the available experimental data for 28 Ni29– 28 Ni50 isotopes and 29 Cu50– 50 Sn50 isotones. The fit procedure, properties of the determined effective interaction as well as new results for valence-mirror symmetry and seniority isomers for...
متن کاملExotic rotations and seniority isomers in Nd nuclei
The existence of triaxial nuclei has been the subject of a long standing debate. The possibility of soft and rigid triaxiality has been proposed very early, and many theoretical and experimental studies have been devoted to this intriguing phenomenon since then. More recently two unique fingerprints of triaxiality in nuclei have been intensively studied: the wobbling motion [1] and the dynamic ...

Abstract Background: Most animal studies have shown that trans-10 and cis-12 isomers of Conjugated linoleic Acid, (CLA) tend to increase insulin resistance. But the effect of equal isomers of CLA (50:50 ratios of cis-9, trans-11: trans-10, cis-12 isomers) on lipid profiles, glucose, and insulin resistance and sensitivity in postmenopausal women is not clear. Methods: In the present study, ...
