dc.description.abstractEn | We report the first high-precision mass measurements of the neutron-rich nuclei <sup loc="post">74,75</sup>Ni and the clearly identified ground state of <sup loc="post">76</sup>Cu, along with a more precise mass-excess value of <sup loc="post">78</sup>Cu, performed with the double Penning trap JYFLTRAP at the Ion Guide Isotope Separator On-Line (IGISOL) facility. These new results lead to a quantitative estimation of the quenching for the <math altimg="si1.svg"><mi>N</mi><mo linebreak="goodbreak" linebreakstyle="after">=</mo><mn>50</mn></math> neutron shell gap. The impact of this shell quenching on core-collapse supernova dynamics is specifically tested using a dedicated statistical equilibrium approach that allows a variation of the mass model independent of the other microphysical inputs. We conclude that the impact of nuclear masses is strong when implemented using a fixed trajectory as in the previous studies, but the effect is substantially reduced when implemented self-consistently in the simulation. | |
