J., García Ramos, J.E... [et al.] : "Scattering of (6)He at energies around the Coulomb barrier". Journal of Physics G: Nuclear and Particle Physics. Vol. 31, n. 10 Special Issue S1953-S1958 (2005). ISSN 0954-38990954-3899http://hdl.handle.net/10272/5535We have measured elastic cross sections of the scattering of 6He at ELab = 14, 16, 17, 18, 22 MeV on 208Pb in the angular ranges of 20± − 64± and 135± − 170±. A significant amount of 4He events is found at energies well below the Coulomb barrier, that becomes dominant above it. Optical Model calculations have been performed including a dynamic polarization potential. Very large imaginary diffuseness parameter is needed in order to describe the experimental distributionsengAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Física nuclearCoulomb barrierjournal article10.1088/0954-3899/31/10/109open access
