摘要

Our analysis reveals the significant influence of continuum states in close proximity to the resonant pole on both phase shifts and continuum level densities. Specifically, the uppermost and lowest continuum states, located just above and below the resonant pole, make substantial contributions to the scattering quantities. Conversely, the continuum state located farthest from the resonant pole has a negligible impact. These findings underscore the crucial role of continuum state structure in understanding physical observables in light nuclei. This work focuses on a detailed investigation of the \(3/2^-\) 3 / 2 - state \(^5\) 5 Li.
