The ground state rotational band populations for the 4[ital n] evaporation channel have been measured at three [sup 16]O bombarding energies. The populations for the [sup 4]He+[sup 166]Er reaction, which populates the same residual nucleus at above-barrier energies, have also been measured to calibrate the statistical model which has been used to relate the observed populations to the compound nuclear spin distribution. The mean compound nuclear angular momenta are somewhat less than obtained in a previous gamma ray multiplicity investigation and are in better agreement with coupled channels calculations.
