Spreading widths of giant monopole resonance in the lead region: Random matrix approach
N. N. Arsenyev, A. P. Severyukhin, R. G. Nazmitdinov
The microscopic calculation of the decay width of giant monopole resonance (GMR) anticipates the mixing of one-phonon states with configurations of increasing complexity. To this a…
