The projected functions of the coherent state model (CSM) describing the ground, gamma and beta bands are studied in the intrinsic frame of reference. Several symmetry relations for the intrinsic functions are obtained. Analytical expressions for the matrix elements of the collective operatorβm+ncosmγsinnγ are derived. Important selection rules are established for them.read more

Coupling of two quasiparticles to coherent cores in the Pt isotopes
TL;DR: In this paper, a model for coupling the motion of particles to that of a quadrupole-collective core is proposed, where the quadrupoles vibrations and rotations of the core are described by angular momentum projected coherent states.

Low-lying octupole bands in the coherent state model
TL;DR: In this paper, the properties of the Kπ = 0−, 1−, 2− octupole bands in actinides and few rare-earth nuclei are studied within the coherent state model using an effective Hamiltonian defined in a space spanned by six rotational bands.

Low-lying bands as alpha-like dipole excitations of a coherent quadrupole boson state
TL;DR: A phenomenological analysis of low-lying positive and negative-parity bands of some heavy deformed nuclei is carried out within a coherent-state model by making use of an interacting boson Hamiltonian where quadrupole bosons associated to the nucleon motion are coupled to scalar and dipole Bosons introduced to describe the motion of α-clusters with respect to a deformed nuclear core as mentioned in this paper.

TL;DR: In this paper, a unified description of collective nuclear states in terms of a system of interacting bosons was proposed, and both the vibrational and the rotational limit can be recovered within this model.

“Shells” in deformed nuclei
V.M. Strutinsky,V.M. Strutinsky +1 more
TL;DR: In this article, the shell correction method was used to calculate the effect of nucleon shells in deformed and spherical nuclei, and the results were presented in such a way as to illustrate more clearly the effects of shell shells on nucleon nuclei.

TL;DR: In this paper, a theory of the energy states and the electromagnetic transitions between them for nuclei which do not possess axial symmetry was developed and the reduced probabilities for E2 and M1 transitions between various rotational states were computed.

Surface oscillations in even-even nuclei

TL;DR: In this paper, surface oscillations in nuclei with deformation potentials independent of the shape parameter are discussed, and the regularities in even-even nuclei of the type discussed by Scharff-Goldhaber and Weneser are described.

Particle Derivation of Nuclear Rotation Properties Associated with a Surface Wave
TL;DR: In this paper, the collective rotational energy was derived from a suitable set of nucleon wave functions in the approximation in which there is a rotating distortion, slow compared with the internal nucleon motions.
