and 200 GeV energy the higher mass range 5 < m < 10 GeV is explored. x The lower masses are measured at 4$0 with lower incident energy as well as o by the detectors located closer to 90 • (4) The mass resolution is calculated on the basis of a 50 keV energy resolution in the detectors. (5) The fonn-factor squared for deuteron break up is exp (q2R2/3). Note that significant damping of the cross section does not appear until m ~ x -5­ Figure Captions Fig
