Abstract
Data taking for this experiment was completed in December 1983. The samples include approximately 19,000 ({nu}) and 11,000 ({nu}-bar) charged current events. These constitute the largest data set of interactions on free protons. Work published to date includes studies of inclusive structure functions and final state properties, exclusive final states, neutral current cross sections and production of strange and charmed particles. During the past year results have been published on the production of f{sub 2} (1270) and {nu}{sup 0} (770) mesons in {rho}p and {rho}-barp charged current interactions. In the case of the f{sub 2} this represents the first observation of such production. It is found that the multiplicities are 0.047{+-}0.017 in {rho}p and 0.17{+-}0.018 in {rho}-barp. The f{sub 2} mesons are mostly produced at large hadronic invariant mass W and in the forward hemisphere. The production of {nu}{sup 0} mesons can be observed with high statistics in both {rho}p and {rho}-barp interactions and the differential cross section studied. The observations are compared with LUND Monte Carlo predictions, which are generally found to be too high. However qualitative features of the data are reproduced. Work continues on a precise determination of the neutral current/charged current ratio, on the study of
