TITLE=/Measurement of the differential cross section for the reaction
pi+ + d -> p + p at momenta between 0.48 and 1.16 GeV/c/;
PURPOSE=/To measure the differential cross section for pi+ d -> pp at
pion momenta P(pi) from 0.48 and 1.16 GeV/c and seven CM
angles, 6 deg., 14 deg., 23 deg., 31 deg., 40 deg., 52 deg.
and 61 deg./;
