Approximate approaches to problems of a resonating group model
The functional efficiency of various versions of the resonating group model (RGM) and its approximations for describing deep subbarrier resonances were studied. A number of approaches convenient for calculations of such states in RGM and the orthogonality conditions model (OCM) are proposed. A model that, on the one hand, is relatively simple to use and, on the other hand, produces a satisfactory description of resonance widths is found. The model seems to be promising for studying the α decay of heavy nuclei.
