    What "quenches" in nuclei ?

    Mannque Rho🇫🇷

    The answer is found in the way the hidden scale symmetry involving a dilaton emerges in strong nuclear correlations in nuclear matter. It is suggested that the same mechanism is at the origin at higher densities of the sound speed converging in the core of massive compact stars to what could be called ``pseudo-conformal sound speed" . A precision measurement of the superallowed Gamow-Teller transitions in the doubly magic nucleus Sn is suggested to confirm or falsify this prediction. It could also lead to the possible determination of genuine ``fundamental renormalization" of in nuclear medium.

    Ab initio study of resonance states of exotic 10Li nucleus

    Dmitry Rodkin · Yury Tchuvil'sky

    The spectrum, partial and total decay widths of the states of the exotic 10Li nucleus are studied in an ab initio approach. The spectrum is calculated using No-Core Shell Model and corresponding extrapolation procedure. The calculations use the well-proven Daejeon16 potential. The NCSM-based approach, which includes a method for constructing the basis of functions of cluster channels and a procedure for matching the cluster form factors obtained within this method with the asymptotic wave functions, is applied to compute the widths of the levels. The results obtained quite adequately reproduce the pattern given by the most advanced experiments. Detailed predictions of the spectral characteristics of 10Li nucleus states are given.
