Nuclear shape coexistence is the phenomenon in which distinct shapes occur within the
same nucleus and at a similar energy. In this work, we provide an overview of the …

Shape coexistence in nuclei appears to be unique in the realm of finite many-body quantum
systems. It differs from the various geometrical arrangements that sometimes occur in a …

Signatures of criticality in the evolution of the nuclear ground-state shapes across the N× Z
plane are discussed. Attention is paid to specific data indicating sudden structural changes …

A systematic analysis of low-lying quadrupole and octupole collective states is presented
based on the microscopic energy density functional framework. By mapping the deformation …

We report on the first γ-ray spectroscopy of low-lying states in neutron-rich Kr 98, 100
isotopes obtained from Rb 99, 101 (p, 2 p) reactions at∼ 220 MeV/nucleon. A reduction of …

A quantitative analysis of the evolution of nuclear shapes and shape phase transitions,
including regions of short-lived nuclei that are becoming accessible in experiments at …

The possibility of the existence of octupole deformation in Pm 151 has caused interest for
about thirty years. In this paper, the observed low-lying positive-and negative-parity …

Collective quadrupole and octupole states are described in a series of Sm and Gd isotopes
within the framework of the interacting boson model (IBM), whose Hamiltonian parameters …

We review the current experimental data on collective structures within the pairing gap of
even-even deformed nuclei, with emphasis on nuclei near mass number A∼150 A∼ 150 …

We have used the (α, 2 n) and (α, 4 n) reactions and the AFRODITE γ-ray spectrometer to
make a comprehensive study of the nucleus 154 Gd below \ensuremath20ℏ. While the first …
