The deviation of the ionic background potential in simple metal clusters from the harmonic shape leads to a red shift of the surface plasmon from the Mie frequency, that is considerably larger than the spill-out correction. In order to estimate this effect, here we develop a variational approach to

Atomic nuclei and simple metal clusters exhibit several surprising similarities. Some of the cluster properties are discussed, which have an analogue in nuclear physics, such as magic numbers, single and collective excitations, higher excitations of the Giant Dipole Resonance, etc. As an example of
Early development of the instabilities in a dilute nuclear source is investigated using a finite temperature quantal RPA approach for different systems. The growth rates of the unstable collective modes are determined by solving a dispersion relation, which is obtained by parametrizing the transitio
A fully consistent relativistic random phase approximation (RRPA) built on the relativistic mean field (RMF) ground state is applied to study the giant multipole resonances of stable nuclei. The fully consistent RRPA requires that the nuclear RMF wave function and the RRPA renormalization are calcul
