Description: We have performed the coincidence experiments (..cap alpha..,..cap alpha..'f) and (..cap alpha..,..cap alpha..'nf) on /sup 238/U for a beam energy E/sub ..cap alpha../ = 120 MeV and for ..cap alpha..-scattering angles theta/sub ..cap alpha..'/ = 9/sup 0/, 15/sup 0/, and 17/sup 0/. The 9/sup 0/ and 17/sup 0/ data correspond to maxima in the angular distribution for the isoscalar giant quadrupole resonance, whereas the 15/sup 0/ data lie close to a minimum. Using a set of fission counters which covered roughly 80% of 4..pi.., we were able to reject neutrons associated with fission in the (..cap alpha..,..cap alpha..'n) spectrum. We present a first look at these spectra. 9 refs., 3 figs.
