Study of the nuclear matter distribution through $alpha$ particle scattering by cadmium, tin, tellurium, samarium, and lead isotopes near the Coulomb barrier (in French)

OSTI ID:4134711
The aim of this study was to establish the existence of an $alpha$- nucleus interaction radius in the elastic scattering of $alpha$ particles at energies near to the Coulomb barrier, and to obtain informations on matter distribution inside the nucleus. Measurements were carried out on the following twenty three nuclei: cadmium 110, 112, 114, 116, tin 112, 114, 116, 118, 120, 122, 124, tellurium 122, 124, 126, 128, 130, samarium 144, 148, 150, 152, and lead 204, 206 and 208. It was effectively possible to determine an $alpha$- nucleus interaction radius, corresponding to a well defined nuclear potential, and whose slope as a function of Asup(1/3) is of the order of 1,36fm. It was also possible to connect this nuclear potential to matter distribution and to determine inside this distribution a point where the nuclear density has a definitive value. A confirmation is given that neutrons in excess are preferentially distributed at the surface of nuclei and, a consequence, make this surface more diffuse. (FR)
