Title: Reaction cross sections and radii for f-p shell exotic neutron-rich nuclei

Abstract

Reaction cross sections have been measured at energies ranging from 50 to 70 MeV/nucleon for a variety of exotic neutron rich isotopes of Ar, K, Ca, and Sc. A method where Si detectors are used also as targets has been utilized for the measurements. The strong absorption radii r{sub 0}{sup 2} have been determined and compared to the results of Glauber-type calculations which used density distributions extracted from the relativistic mean field theory. The isospin dependence of the radii was investigated and a trend similar to the one for lighter nuclei has been observed. The possible existence of halo or skin nuclei has also been addressed. {copyright} {ital 1997} {ital The American Physical Society}
