Abstract
We have recently implemented a fully self-consistent model based on Quasiparticle-Vibration Coupling (QPVC model). This can be applied to Giant Resonances of any kind, and can account for the position of the resonance main peak (or centroid) and for the resonance width. In this contribution, we show how this model can solve the problem of the different incompressibilities (K∞) that spherical nuclei display. In other words, we discuss here that the values of K∞ extracted from Sn isotopes and 208Pb turn out to be compatible, so that the famous issue of the “fluffiness” of Sn is set. Ca isotopes and 90Zr are also compatible with the same values of K∞, that are around 225–230 MeV. This conclusion relies on the use of the so-called subtraction method.
