In the frame of a systematic study of hadron-nucleus interactions performed at the Serpukhov accelerator (CERN-IHEP 5th experiment), semicoherent elastic scattering on carbon pi- C12 -> pi- C12(4.44 MeV) was investigated with 25 and 40 GeV/c incident pions.

Abstract

In the frame of a systematic study of hadron-nucleus interactions performed at the Serpukhov accelerator (CERN-IHEP 5th experiment), semicoherent elastic scattering on carbon pi- C12 -> pi- C12(4.44 MeV) was investigated with 25 and 40 GeV/c incident pions. The experimental data were obtained with a counter technique, looking at the coincidence between the scattered pion and the 4.44 MeV photon from the JP = 2+ carbon excited state detected by a NaI counter. The value obtained for the integrated cross section at 40 GeV/c in the 0.0032 ⩽ |t| ⩽ 0.27 (GeV/c)2 four-momentum transfer range is σ = 1.16 ± 0.11 mb. According to the theoretical models, this t-range at 40 GeV/c covers more than 99% of the angular distribution, so the above value almost corresponds to the total semicoherent elastic cross section.
