Measurements were made of the parameters of nine low energy neutron resonances in tungsten. The results from neutron transmission, elastic scattering, and capture gamma -ray experiments were combined to obtain accurate values for the neutron and radiation widths, and, for W/sup 183/, of the spins of the excited levels. For W/sup 183/ the resonances at 7.62, 27.1, 46.1, 47.7, and 100.8 ev were found to have spin 1, 1, 1, 0, and 0, respectively. The average value for the radiation widths for the levels with spin 0 and spin 1 were the same within the experimental error. For the three tungsten isotopes 182, 183, and 186 the average radiation widths were 50 plus or minus 4, 73 plus or minus 4, and 45 plus or minus 6 Mev, respectively. These values do not agree with the observation that the average radiation widths are roughly proportional to the fourth power of the binding energy. (auth)
