| Popis: | Positive pions and protons emitted at 90° were measured in coincidence with two fission fragments in the reaction 16 O + 232 Th at 95 MeV/nucleon. The linear momentum transfer distribution has been determined from the folding angle between the fragments. The average momentum transfer is 2.5 GeV/ c ± 0.2 GeV/ c for a pionic reaction. An analysis in terms of impact parameter distributions leads to the conclusion that subthreshold pion production requires a large overlap of projectile and target density profiles. |
