Triaxiality and exotic rotations at high spins inCe134

Nuclear Structure at High Spins

Nuclear structure at the highest spins is very likely to involve both collective and single-particle aspects. The liquid-drop model favors shapes that imply combinations of collective (rotational) and rotation-aligned single-particle angular momenta. The detailed band structures for the full range of such mixtures are considered. Nuc le i are composed o f a smal l ( b u t n o t t o o sma l l ) ...

Nuclei at High Spins : a Summary

Exotic 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 ...

Exotic stable cesium polynitrides at high pressure

New polynitrides containing metastable forms of nitrogen are actively investigated as potential high-energy-density materials. Using a structure search method based on the CALYPSO methodology, we investigated the stable stoichiometries and structures of cesium polynitrides at high pressures. Along with the CsN3, we identified five new stoichiometric compounds (Cs3N, Cs2N, CsN, CsN2, and CsN5) w...

BRST treatment of the Bohr collective hamiltonian at high spins

The BRST treatment of triaxial systems rotating at high spins is used to solve perturbatively the γ-independent Bohr collective hamiltonian.
