ISSN 0375-94740375-9474http://hdl.handle.net/10272/5530The elastic scattering of 6He on 208Pb has been measured at laboratory energies of 14, 16, 18 and 22 MeV. These data were analyzed using phenomenological Woods- Saxon form factors and optical model calculations. A semiclassical polarization po- tential was used to study the e ect of the Coulomb dipole polarizability. Evidence for long range absorption, partially arising from Coulomb dipole polarizability, is reported. The energy variation of the optical potential was found to be consistent with the dispersion relations which connect the real and imaginary parts of the potential.spaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Física nuclearNuclear reactionsOptical model parametersCoulomb dipole polarizabilityDispersion relationsThreshold anomalyRadioactive beamjournal article10.1016/j.nuclphysa.2008.01.030open access
