Differential Cross Sections

for unpolarized target and without recoil polarization

The following notation of the coincidence cross section will be used in our calculations. Further details can be found in D. Drechsel and L. Tiator, J. Phys. G 18 (1992) 449-497. (scanned version)

On this page only the individual 2-fold cross sections ST, SL, SLT, STT and SLT' will be calculated. For a calculation of the complete 5-fold differential cross section see our alternative page.
Note: The longitudinal cross sections (SL, SLT and SLT') differ from those in Drechsel and Tiator, J. Phys. G18 (1992) 449. Here we do not use the longitudinal polarization epsilon_L.

Channel: (pi0,p) (pi0,n) (pi+,n) (pi-,p)
