DOI: 10.1103/physrevc.100.014316
Abstract: In nuclear structure calculations, the choice of a limited model space, due to computational needs, leads to the necessity to renormalize the Hamiltonian as well as any transition operator. Here, we present a study of… read more here.

DOI: 10.1103/physrevc.95.054320
Abstract: We report on the β-delayed neutron emission probability (P1n) measurements of the Ga82,83,84 (N=51,52,53) precursors performed in one single experiment using the He3 neutron-counter TETRA at the ALTO facility in Orsay. Altogether our results for… read more here.

DOI: 10.1103/physrevc.97.054326
Abstract: The isoscalar neutron-proton pairing is thought to be important for nuclei with equal number of protons and neutrons but its manifestation in structure properties remains to be understood. We investigate the Gamow-Teller (GT) transitions for… read more here.

DOI: 10.1103/physrevlett.121.132501
Abstract: The key parameter to discuss the possibility of the pion condensation in nuclear matter, i.e., the so-called Landau-Migdal parameter g^{'}, was extracted by measuring the double-differential cross sections for the (p,n) reaction at 216 MeV/u on… read more here.

DOI: 10.1103/physrevlett.123.202501
Abstract: The nuclear response theory for charge-exchange modes in the relativistic particle-vibration coupling approach is extended to include for the first time particle-vibration coupling effects in the ground state of the parent nucleus. In a framework… read more here.

DOI: 10.1134/s106377882002026x
Abstract: The $$\beta$$ -decay half-life and the delayed neutron emission of $${}^{60}$$ Ca are studied within a microscopic model, which is based on the Skyrme interaction T45 to construct single-particle and phonon spaces. We observe a… read more here.
