Question:
A liquid hydrogen target of volume 125 cm3 and density 0.071 g/cm3 is bombarded with a mono energetic beam of negative pions with a flux 2 × 107/m2 s and the reaction π− + p → π0 + n observed by detecting the photons from the decay of the π0 . Calculate the number of photons emitted from the target per second if the cross-section is 40 mb.
