【 摘 要 】

Bi2Sr2CaCu2O8+delta crystals with varying hole concentrations (0.120.12. Based on the magnitude of the B-1g renormalization, it is found that the number of quasiparticles participating in pairing increases monotonically with increased doping. On the other hand, the B-2g spectra show a weak pair-breaking peak that follows a paraboliclike dependence on hole concentration, for 0.12
