Arch behaviour of charge radii of Ca isotopes has been a long standing problem in nuclear theory. Recently, it was proposed that the Fayans pairing is a possible solution to obtain it using nuclear density functional theory. In this talk, we will explain the mechanism why the Fayans pairing can show the arch behaviour.

The self-consistent mean-field calculation with semi-realistic interactions has predicted that N=58 becomes a magic number at Ni, at which n2s1/2 is the highest occupied orbit. Thereby, Ni-86 can be very distinguished, as it is a doubly-magic nucleus and possesses a neutron halo simultaneously. With the least ambiguities in the many-body wave function, it may provide a unique opportunity to...

We aim to investigate mesonic effects in nuclei by measuring B(M1) values for l-forbidden (Δl = 2, ΔJπ = 1⁺) transitions. The transition strengths were obtained from level lifetimes measured using the line-shape analysis method with Ge detectors. In this study, we performed two in-beam γ-ray spectroscopy experiments to determine the lifetimes of the first excited states in 39Cl (CAGRA...

The rapid neutron capture process, r-process, is responsible for the production of more than half of the elements heavier than iron. However, the physical conditions and astronomical sites of the r-process have not yet been determined. The lack of experimental data on the properties of the involved exotic nuclei is a significant source of uncertainty. In particular, the difficulty of directly...
