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 …

The last decade has witnessed both quantitative and qualitative progress in shell-model
studies, which have resulted in remarkable gains in our understanding of the structure of the …

The monopole effect of the tensor force is presented, exhibiting how spherical single-particle
energies are shifted as protons or neutrons occupy certain orbits. An analytic relation for …

The properties of exotic nuclei on the verge of existence play a fundamental part in our
understanding of nuclear interactions. Exceedingly neutron-rich nuclei become sensitive to …

Experimental results of E2 transition probabilities or B (E2) values for the known first 2+
states in 447 even–even nuclei have been compiled and evaluated. The evaluation policies …

Neutrino–nuclear responses associated with astro-neutrinos, single beta decays and double
beta decays are crucial in studies of neutrino properties of interest for astro-particle physics …

Novel simple properties of the monopole component of effective nucleon-nucleon
interactions are presented, leading to the so-called monopole-based universal interaction …

We present a new effective interaction for shell-model calculations in the model space
consisting of the single-particle orbits 1 p 3/2, 0 f 5/2, 1 p 1/2, and 0 g 9/2. Starting with a …

The shell-model effective interaction GXPF1 is tested for the description of unstable pf-shell
nuclei. The GXPF1 successfully describes the N= 32 shell gap in Ca, Ti and Cr isotopes …

Nuclear charge radii of Ni 55, 56 were measured by collinear laser spectroscopy. The
obtained information completes the behavior of the charge radii at the shell closure of the …
