Zero-degree excitation functions of evaporation residues formed primarily by neutron boiloff from the /sup 206/Rn compound nucleus in the /sup 37/Cl+/sup 169/Tm fusion reaction were measured from 148.5 to 186 MeV beam energy. The evaporation residues were identified by their alpha-decay energies. Cross sections associated with 2n, 3n, 4n, 3n1p, 5n, and 4n1p emission peak at 155, 157, 165, 168, 177, and 182 MeV, respectively. 3n1..cap alpha.. emission was also observed and shows hints of forward-backward asymmetry. A maximum total evaporation residue cross section of 1.6 +- 0.5 mb was observed at 165 MeV. A comparison of these results to statistical evaporation theory predictions was made, showing fair agreement, except for the 2n cross section which was considerably larger than predicted.
