Structure of 8Li from a reaction cross-section measurement.

We have precisely measured reaction cross sections (R) for 8Li using 9Be, 12C, 27Al, and proton targets at intermediate energies by the transmission method. From the energy dependence of the R including the high energy data, the density distribution of 8Li was deduced through a modified Glauber model. It is shown that 8Li has a shorter tail structure in the density as compared with that of 8B and the matter radius of 8Li is similar to those of the other nonhalo Li isotopes. The result is consistent with the previous experiments that there is a tendency for 8Li to be a skin nucleus. [ABSTRACT FROM AUTHOR]
