Prediction of the shapes of deformed nuclei by the polyspheron theory.
It is pointed out that some features of the shapes of (62) (154)Sm, (68) (166)Er, and (70) (176)Yb as reported by Cooper et al. [Cooper, T., Bertozzi, W., Heisenberg, J., Kowalski, S., Turchinetz, W., Williamson, C., Cardman, L., Fivozinsky, S., Lightbody, J., Jr., & Penner, S. (1976) Phys. Rev. C 13, 1083-1094] from electron-scattering experiments agree reasonably well with the description of these nuclei, derived from the values of the rotational energy levels, as consisting of a large spherical part (essentially (132)Sn) and a cap [Pauling, L. (1969) Proc. Natl. Acad. Sci. USA 64, 807-809; Pauling, L. & Robinson, A. B. (1975) Can. J. Phys. 53, 1953-1964].
