Evaporation residue products from reactions withKr86

Cross sections for evaporation residue products have been measured from ${}_{}{}^{86}{}_{}{}^{}\mathrm{Kr}$-bombardments of ${}_{}{}^{65}{}_{}{}^{}\mathrm{Cu}$, ${}_{}{}^{90}{}_{}{}^{}\mathrm{Zr}$, and ${}_{}{}^{109}{}_{}{}^{}\mathrm{Ag}$ at energies ranging from 366 to 716 MeV. In the ${}_{}{}^{65}{}_{}{}^{}\mathrm{Cu}$ and ${}_{}{}^{90}{}_{}{}^{}\mathrm{Zr}$ cases, experimental ${\sigma }_{\mathrm{ER}}$ values are in agreement with predictions of statistical model deexcitation calculations in which angular-momentum-dependent fission competition has been included. The measured ${\sigma }_{\mathrm{ER}}$ is considerably lower than the calculated value for ${}_{}{}^{109}{}_{}{}^{}\mathrm{Ag}$ + ${}_{}{}^{86}{}_{}{}^{}\mathrm{Kr}$, but predictions are extremely sensitive to level density parameters in that case. Correlated mass-charge distributions of evaporation residue products have been measured from the reaction ${}_{}{}^{65}{}_{}{}^{}\mathrm{Cu}$ + ${}_{}{}^{86}{}_{}{}^{}\mathrm{Kr}$ at 316 and 716 MeV. At the higher energy, measured and calculated distributions are in excellent agreement with each other, and calculations are insensitive to assumptions made concerning the effect of particle emission on the angular momentum of the evaporating system. At the lower energy, measured distributions are broader than calculated ones, and the theory is sensitive to specific assumptions concerning angular-momentum removal.
