Abstract: | We study the reaction cross sections(σR)and root-mean-square(RMS)radii of 8Li and 8B,the halo-like nuclei,with stable target 12C,27Al and 9Be within the standard optical-limit Glauber model,using densities obtained from relativistic mean-field(RMF)formalisms and other types of distributions.It is found that the experimental σR can be reproduced well at high energy.The RMS radius and Δr extracted by RMF-theory and harmonic oscillator distribution are compared.We find that the RMS radius and △r of 8B are larger than those of 8Li.In addition,we analyze in detail the relationship between σR and density distribution. |
