Breakthroughs in our treatment of the many-body problem and nuclear forces are rapidly transforming modern nuclear theory into a true first-principles discipline. This allows us to address some of the most exciting questions at the frontiers of nuclear structure and physics beyond the standard model.
In this talk I will briefly outline our many-body approach, the valence-space in-medium...
I will review research activities ongoing in Japan related to low-energy electron scattering conducted for nuclear physics will be presented. These include electron scattering for proton charge radius measurement (ULQ2) and for structure studies of short-lived exotic nuclei (SCRIT).
ULQ2 (Ultra-Low Q2) for proton charge radius
Electron scattering off proton covering an extremely low...
Intruder states that originate from the promotion of neutrons across the N=50 shell gap are observed along the N=49 isotones ($^{79}$Zn, $^{81}$Ge, $^{83}$Se, $^{85}$Kr), with the lowest energy in $^{83}$Se. The reduction of the N=50 shell gap towards $^{78}$Ni favors the lowering in the energy of these states. Moreover, since the $^{83}$Se nucleus (Z=34) is in the middle of the proton...
The shell structure of nuclei is the backbone of the nuclear theory. A large energy gap with the completely filled spherical orbitals defines shell closure and magic number. One of the intriguing experimental findings is the disappearance of shell closure at certain N and Z, which is not predicted from the classical shell model. This Island of Inversion (IOI) has been successfully explained...
The character of nuclear superfluidity and the isospin modes of nucleonic pair correlations is a longstanding problem of large interest in nuclear structure physics.
In recent years, intermediate-angular momentum states in heavy N~Z nuclei such as 88Ru are becoming accessible with advances in instrumentation, most notably the new generation of -ray tracking arrays.
The low-lying energy...
The atomic nucleus is a complex many-body system, with behaviour dictated predominantly by the strong nuclear force. These features give rise to the emergent property of nuclear collectivity, in which the nucleus deviates from sphericity, becoming deformed. Understanding the onset of this deformation, predominantly in its quadrupole and octupole forms, therefore requires modelling both the...
In the present work, we explored the nuclear structure of three quasiparticle (3qp) quadruplets observed in deformed odd-A nuclei lying in the rare-earth mass region and assigned the most probable 3qp configuration among various possible competing configurations suggested in the literature. To accomplish our objectives, we have adopted a semi-empirical model formulation that includes all the...
