Position and width of the monopole giant resonance in 208Pb

The positions and widths of the monopole giant resonances in 208Pb are calculated. The calculated widths include the effects of the single particle decay width and of the spreading width. We find the isoscalar resonance at Esub(res) approximately equal to 13.0 MeV, while the isovector resonance is found at Esub(res) approximately equal to 20.5 MeV. Due to the asymmetry of the resonance curves an unambiguous value for the widths cannot be defined. Instead we present the form of the resonance curve in numerical form in table 1. (orig.)
