Coexistence in even-mass nuclei
TL;DR: In this article, two main theoretical approaches for shape coexistence in doubly even nuclei are presented, the shell model and the deformed mean field approach, which is broadly defined so that it includes various truncation schemes, including generalized seniority and the interacting boson model.

Pairing in Nuclear Systems: From Neutron Stars to Finite Nuclei
D. J. Dean,Morten Hjorth-Jensen +1 more
TL;DR: In this article, the links between many-body pairing as it evolves from the underlying nucleon-nucleon interaction and the eventual experimental and theoretical manifestations of superfluidity in infinite nuclear matter and of pairing in finite nuclei are discussed.

Coriolis effects in the yrast states
F.S. Stephens,R.S. Simon +1 more
TL;DR: In this paper, the Coriolis effects at high angular momentum in a system consisting of two (or four) particles in the i 13 2 orbital coupled to a deformed core were investigated, and they found that the particles tend to decouple from the core and add their angular momenta, ultimately 2j−1 for two particles, directly to that produced by the rotation of the core.

The Clover: a new generation of composite Ge detectors
G. Duchêne,F.A. Beck,P.J. Twin,D. Curien,L. Han,C. W. Beausang,M. A. Bentley,P. J. Nolan,J. Simpson +8 more
TL;DR: In this paper, the authors present the characteristics of a new generation of composite germanium detectors: the Clover detector, which is based on simulation calculations performed with the code GEANT3, and an extensive study of its main characteristics involving the photopeak detection capabilities, energy resolution and timing performed with sources and in-beam experiments have been measured.

Nuclear moment of inertia at high rotational frequencies
A. Johnson,H. Ryde,S.A. Hjorth +2 more
TL;DR: In this paper, the rotational moments of inertia of doubly even well-deformed nucleides were investigated in (α, x n) reactions and the variation of the moment of inertia with rotational angular velocity was investigated.

Effect of Nuclear Rotation on the Pairing Correlation
Ben R. Mottelson,J. G. Valatin +1 more
TL;DR: In this article, the effect of nuclear rotation on the pairing force in low excited states of deformed nuclei was investigated by using the generalized Hartree-Fock method (used in superconductivity theory) to study the quantum mechanics of a reference system rotating with a rotational angular momentum.

Strongly perturbed positive-parity bands in odd-mass erbium isotopes
TL;DR: In this paper, the authors used alpha-particle irradiation of enriched dysprosium targets to populate states in 161 Er, 163 Er and 165 Er Cascade and crossover transitions are observed within a strongly perturbed rotational band which is populated up to spin 25 2.

Location and description of some low-lying high-spin states in 155Gd
TL;DR: In this article, the authors used the reaction 154 Sm(α, 3n) 155 Gd to populate states in the positive-parity band and observed Cascade and crossover transitions within a strongly perturbed rotational band.
