The angular distributions for the scattering of negative pions by liquid deuterium were measured, using the 119-Mev pion beam of the Chicago cyclotron and scintillation counters. The values of the nonexchange scattering differential cross section in the laboratory system for angles of 45°, 90°, and 135° are 8.50±0.31, 5.31=fc0.20, and 8.36±0.29 in units 10~2 7 cm 2 steradian" 1 . The differential cross sections for the production of photons at the same angles and in the same units are 2.20±0.27, 2.41 ±0.28, and 3.40±0.38. The total cross section from transmission measurements is (132±7)X10 _27 cm 2 . These values are somewhat less than the sum of the previously measured cross sections for positive and for negative pions on hydrogen.

“…1-11 The principal results of these calculations are in good agreement with experimental observa- tion. [12][13][14][15][16][17][18][19][20][21][22][23][24] However, in the region of high momenta it is uncertain how much of this total energy loss manifests itself as ionization and how much as Cerenkov radiation. Sternheimer, 8 in his treatment of the density-effect corrections to the Bethe-Bloch calculation, has suggested a method to compute this division of energy loss.…”
