Polaron states of electrons in clusters //Bulletin of the Russian Academy of Sciences. Physics, 1995, v.59, №8, p.1391-1394

      Exact spherical-symmetric solutions to polaron equations are found for a cluster. It is shown that there are two different types of the solutions, corresponding to two different ground states. One of them describes electron localization inside the cluster, while the other is for the state in which electron density is mainly distributed outside the cluster. There is a critical cluster size below which the localized states are absent. At the critical point a bifurcation of solutions takes place. For water clusters the energy of interior electron states falls' into the observed range of experimental data.
