Evaporation residue excitation functions of the reaction {sup 19}F + {sup 93}Nb {r_arrow} {sup 112}Sn{sup {asterisk}}, in the bombarding energy range between 54 and 95 MeV, have been measured using the recoil catcher technique. Energy spectra, angular distributions, and correlations between angular anisotropy and ejectile energy of evaporated protons and alpha particles have been measured for the above system at 73 and 95 MeV bombarding energies. The experimental data are compared with the predictions of the statistical model code PACE2 making use of two different level density formalisms. The level density parameters derived from the proton and alpha spectra are presented. The angular-anisotropy ejectile-energy correlations of the alpha particles show a peak in the variation of the anisotropy with the ejectile energy in the subevaporation barrier range. The sensitivity of the angular-anisotropy ejectile-energy correlations to the statistical model parameters is discussed. {copyright} {ital 1997} {ital The American Physical Society}
