Comparison of 120Sn(6He,6He)120Sn and 120Sn(alpha,alpha)120Sn elastic scattering and signatures of the 6He neutron halo in the optical potential

Cross sections of ${}^{120}$Sn($\alpha$,$\alpha$)${}^{120}$Sn elastic scattering have been extracted from the $\alpha$ particle beam contamination of a recent ${}^{120}$Sn(${}^6$He,${}^6$He)${}^{120}$Sn expe…
