✦ Synopsis

Matter and charge distributions for the ground states of ({ }^{5,6,7,9,11} \mathrm{Li}) were calculated in terms of interacting microscopic clusters: the valence clusters (one, two, three particles) and the intrinsic vacuum clusters (collective-excitations of reference vacuum). Root-mean-square matter and charge radii have been extracted and are in good agreement with experimental results. A short description of an atomic-physics experiment for measuring the so-far unknown charge radii of radioactive lithium isotopes is also given.

We develop a model in the framework of nuclear fragmentation at thermodynamic equilibrium which can be mapped onto an Ising model with constant magnetization. We work out the thermodynamic properties of the model as well as the properties of the fragment size distributions. We show that two types of
