Abstract The 7.65 MeV, J π= 0+, second excited state in 12 C is known as the Hoyle-state
after Fred Hoyle. In the 1950s Hoyle proposed the existence of the state in order to account …

Recent developments of physics of nuclear clustering are discussed. Our discussions are
mostly focussed on structural problems because the characteristic feature of the recent …

Certain aspects of the recently proposed antisymmetrized α-particle product state wave
function, or THSR (Tohsaki-Horiuchi-Schuck-Röpke) α-cluster wave function, for the …

We propose a method for determining the nuclear radii for the excited states lying above the
particle breakup threshold based on the diffraction model of scattering. The method is …

The purpose of this article is firstly to review the study of the cluster-gas-like structure,
especially the α-cluster-condensate-like structure, which is a novel type of nuclear structure …

Background: Near-threshold α-clustered states in light nuclei have been postulated to have
a structure consisting of a diffuse gas of α particles which condense into the 0 s orbital …

In this article we review the present status of α clustering in nuclear systems. First of all, an
important aspect is condensation in nuclear matter. Like for pairing, quartetting in matter is at …

A container picture is proposed for understanding cluster dynamics where the clusters make
nonlocalized motion occupying the lowest orbit of the cluster mean-field potential …

The 4 α condensate state for O 16 is discussed with the Tohsaki-Horiuchi-Schuck-Röpke
(THSR) wave function which has α-particle condensate character. With a treatment of …

An experimental way of testing Bose-Einstein condensation of α clusters in the atomic
nucleus is reported. The enhancement of cluster emission and the multiplicity partition of …
