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 …

Electric monopole, E 0 transitions in nuclei are reviewed. Values for ρ 2 (E 0)× 1 0 3, X (E
0/E 2) and q K 2 (E 0/E 2) are tabulated. Particular attention is paid to a complete re …

A novel dual–shell mechanism for the phenomenon of shape coexistence in nuclei within
the Elliott SU (3) and the proxy-SU (3) symmetry is proposed for all mass regions. It is …

The shape of a nucleus is one of the fundamental nuclear properties. We perform a
systematic investigation of bubble nuclei that also exhibit shape coexistence in Hf, W, Os, Pt …

Large-scale shell-model calculations have been performed to study the nuclear structure
properties of Hg isotopes with mass varying from A= 193 to A= 200. The shell-model …

We present a review of the electronic γ-γ “fast-timing” technique in combination with LaBr 3
(Ce) scintillator detectors. The γ-γ fast-timing technique has increased in popularity since the …

This article is devoted to a review of decay properties of excited 0+ states in regions of the
nuclear chart well known for shape coexistence phenomena. Even-even isotopes around …

The present work reports the performance of 1.5′′ x 1.5′′ CeBr 3 cylindrical fast
scintillator detectors, coupled to the Photomultiplier Tube (PMT) Hamamatsu R13089-100 …

Systematics of B (E2) transition rates connecting the first excited 02+ state to the first excited
21+ state of the ground state band in even–even nuclei indicates that shape coexistence of …

Background: Shape coexistence in the Z≈ 82 region has been established in mercury, lead,
and polonium isotopes. For even-even mercury isotopes with 100≤ N≤ 106 multiple …
