Differential cross sections for exclusive π ‾ electro-production from the neutron in the reaction e+d → e′+π ‾+p+p_r have been measured over a broad kinematics range in the BoNuS experiment, where p_r is the recoil proton. The experiment was performed using a radial time projection chamber (RTPC) and the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab Hall B. The RTPC detector was specially built to detect low energy recoil protons and had a valid momentum acceptance from 67 to 250 MeV/c. The differential cross sections for D(e, e′π ‾p)p have been extracted, with the proton detected either by CLAS or by the RTPC. The structure functions σ_T + εσ_L, σ_LT and σ_TT were determined and will be presented in comparison with MAID and SAID predictions.
