Abstract
Energy-integrated reaction cross sections have been measured at energies ra nging from 38 to 80 MeV/nucleon for various exotic neutron-rich isotopes of Al, Si, P, S, Cl, Ar, K, Ca, Sc, and Ti stopping in Si. An experimental te chnique is employed where Si detectors are used for both particle identific ation and to serve as the target material. The reduced strong absorption ra dii r(0)(2) are deduced and compared with other experimental results. The r adius dependence on the neutron number was studied and a trend of increasin g reduced radius with neutron excess was found. This behavior is similar to that seen in lighter systems, although less pronounced than found there. T he implications of this result on the conjectured existence of neutron halo or skin nuclei is discussed. [S0556-2813(99)03609-2].
