We present the basic application of CSM to the properties of the unbound phenomena of light nuclei. In particular, we focus on many-body resonant and non-resonant continuum states observed in unstable nuclei. We also investigate the continuum level density (CLD) in the scattering problem in terms of the Green’s function with CSM. We discuss the explicit effects of resonant and non-resonant contributions in CLD and transition strength functions.Oxford University PressJournal Articleapplication/pdfhttp://hdl.handle.net/2115/82635https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/82635/1/PTEP_2020_12A101.pdf2050-3911Progress of Theoretical and Experimental Physics202012122020-12enginfo:doi/10.1093/ptep/ptaa101https://creativecommons.org/licenses/by/4.0/publisher
