Abstract

The effect of breathing excitations of the triton nucleus on the αt cluster structure is studied by investigating electromagnetic properties of 7Li in terms of a microscopic αt cluster model. An admixture of the triton breathing states makes no remarkable change in the surface clustering of the bound spin-doublet states of 7Li. As far as practical problems, e.g. the radiative capture process with low momentum transfer and the αt scattering problem, are concerned, a standard resonating group wave function, without taking into account the breathing excitations of the triton, gives a substantially good approximation provided that the stability conditions are satisfied for both the constituent nuclei α and t.

      In practice, this can occur, for example, in the processes of cold fusion of nuclei, including those in the synthesis of superheavy elements. We note that the monopole polarization of clusters in the lightest nuclei, i.e., nuclei at the onset of the p-shell, was considered in the framework of such microscopic approach as the method of resonating groups [1–8], and both the quadrupole and monopole polarizations were efficiently treated in its algebraic version [9–17]. These approaches are sufficiently sequential, but their realization is so complicated, that the solution of the problem posed in the present work is practically unreal now.
