The efficiency for detecting positive pions which have been scattered elastically from a target has been calculated for low pion energies. Measurements of the efficiency at pion kinetic energies 12 - 77 MeV were made for a 12" long x 5" diameter NE110 plastic scintillator optically coupled to a Philips XP1040 photomultiplier tube. The efficiencies varied from 94% at 12 MeV to 79% at 77 MeV. / Science, Faculty of / Physics and Astronomy, Department of / Graduate

Pion energies between 30 MeV and 60 MeV have been determined by three methods: magnetic field, range and time of flight. The pion energy was measured to an accuracy 2 # by range and 5 % by the time of flight, and the three methods were consistant with one another. The pions which were used were produced by 500 MeV protons from the TRIUMF cyclotron. The pions were focussed into a beam using the M9 (or stopped π/μ) channel. The bending magnets of this channel define the momentum of the beam particles and thus give one method of determining the pion energy. Differential and integral range curves for aluminum and copper were taken and the differential curves were used to determine the range. In taking the differential curve the effect of stopping plates was examined. In the time of flight method, the leading edge; type discriminator was; found to give; a time walk, due to the different energy-loss; of particles in the plastic scintillator. This has a serious effect in determining the pion energies. However, the constant fraction discriminator was found to give dependable results and the measured energies agreed reasonably well with those of the other methods. / Science, Faculty of / Physics and Astronomy, Department of / Graduate

We have performed a sequential decay analysis of the reaction / (pi)('-)p (--->) (omega)(pi)('0)n / at 8.45 GeV/c in a counter - spark chamber experiment conducted at the Argonne National Laboratory Zero Gradient Synchrotron. The production and decay properties of the B('0) meson are presented, along with the differential cross section for the reaction (pi)('-)p (--->) B('0)n. We present evidence for the existence of the (rho)'(1250) meson (IJ('PC) = 11('--)). Our study of the B('0) production indicates dominance of A(,2) exchange (nucleon spin flip). We have found significant amounts of D-wave in the B('0) (--->) (omega)(pi)('0) decay. The production mechanisms for (rho)'(1250) are similar to those for (rho)(770) production and are dominated by (pi) exchange.
