The cross sections of C-22 are calculated consistently for these target nuclei within a reliable microscopic framework, the Glauber theory. To describe appropriately such a reaction involving a spatially extended nucleus, the multiple scattering processes within the Glauber theory are fully taken into account, that is, the multidimensional integration in the Glauber amplitude is evaluated using a Monte Carlo technique without recourse to the optical-limit approximation. We discuss the sensitivity of the spatially extended halo tail to the total reaction cross sections. The root-mean-square matter radius obtained in this study is consistent with that extracted from the recent cross-section measurement on C-12 target. We show that the simultaneous reproduction of the two recent measured cross sections is not feasible within this framework.American Physical Society (APS)2018-05-23engjournal articleVoRhttp://hdl.handle.net/2115/71454https://doi.org/10.1103/PhysRevC.97.0546142469-9985Physical Review C975054614https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/71454/1/PhysRevC.97.054614.pdfapplication/pdf528.42 KB2018-05-23
