In flight negative pion assessments using time-of-flight technique.
Time-of-flight measurement was applied to obtain the energy spectra of the neutron emitted from tissue-equivalent plastic (TEP) exposed by pi- mesons. The separation of electrons and muons in beams was attempted. Neutrons from TEP exposed by pi- mesons at P pi = 500 MeV/c were separated from gamma-rays by the NE 213 liquid scintillator and the pulse-height analyzer. The double differential cross sections for neutron energy are obtained. The cross sections of the neutron energy distributions show a preponderance of low energy neutrons and a high energy tail extending to approximately 100 MeV.
