| Popis: |
The quadrupole-dipole-dipole-multipole (QDDM) magnetic spectrograph and associated experimental methods employed at the Indiana University Cyclotron Facility for studies of the A (p, π ± ) A + 1 reaction are described. The techniques have been used successfully for extensive measurements of the energy-mass- and state-dependence of (p, π + ) differential cross sections in the near threshold region ( T π = 9 to 60 MeV), and for measurement of the polarization asymmetry in the ( p , π − ) reaction. Backg round levels of about 0.1 nb/sr and an energy resolution of 63 keV fwhm have been achieved. |
