(n,γ) reactions on rare Ca isotopes: Valence-hole - coreexcitation couplings in 47Ca.

Recent results on the structure of ⁴⁷Ca will be presented. The nucleus of interest was populated via the cold-neutron capture ⁴⁶Ca(n,γ) reaction, on a rare ⁴⁶Ca target, during the EXILL experimental campaign at the nuclear reactor of Institut Laue- Langevin in Grenoble. High-resolution γ-ray spectroscopy, performed with a composite array of HPGe detectors, enabled the identification of new transitions deexciting states between the neutron-capture level and the ground state. Experimental data will be compared with a novel microscopic theoretical model, currently under development, specifically designed to describe the low-lying structure of odd-mass nuclei with one valence particle/hole outside a spherical doubly-magic core, using the Skyrme effective interaction self-consistently.
