    "abstract": "In previous work it was shown that the radius of nucleus R is determined by\nthe alpha-cluster structure and can be estimated on the number of\nalpha-clusters disregarding to the number of excess neutrons. A hypothesis also\nwas made that the radius R_m of a beta-stable isotope, which is actually\nmeasured at electron scattering experiments, is determined by the volume\noccupied by the matter of the core plus the volume occupied by the peripheral\nalpha-clusters. In this paper it is shown that the condition R_m = R restricts\nthe number of excess neutrons filling the core to provide the beta-stability.\nThe number of peripheral clusters can vary from 1 to 5 and the value of R for\nheavy nuclei almost do not change, whereas the number of excess neutrons should\nchange with the number of peripheral clusters to get the value of R_m close to\nR. It can explain the path of the beta-stability and its width. The radii R_m\nof the stable isotopes with 12 =\u003c Z =\u003c 83 and the alpha-decay isotopes with 84\n=\u003c Z =\u003c 116 that are stable to beta-decay have been calculated.",
