TITLE=/ Double-pion production induced by deutron-proton collisions
in the incident deutron momentum range 2.1-3.8 GeV/c /;
PURPOSE=/ The purpose of this experiment is (1) to extend the
analysis of d-p interactions to obtain the d-p double-pion
production cross sections, and from them deduce the p-p and
n-p double-pion production cross sections, (2) to analyze
the N-N double-pion production data in terms of various
production mechanisms such as N-N double-pion production
with one nucleon in the deuteron and the other as the
spectator nucleon, and two sequential N-N single-pion
production reactions involving all two nucleons in the
deuteron, and (3) to analyze the d-p double-pion production
reactions as the sum of the N-N double-pion production
reactions and two sequential N-N single-pion production
reactions. /;
