Scattering experiment is done in lab frame but data is reported in center of mass frame Lab system Classically: v cm = (m a v a )/(m a + m x ) Center of Mass system
Cross Section, σ σ = “effective area” of a target nucleus for a certain reaction Units are barns, b = 10 -28 m 2 (or mb = 10 -31 m 2 ) The <strong>to</strong>tal effective area of all nuclei in target = σ (nAt) Rate of reaction = (incoming beam rate) x (<strong>to</strong>tal effective area) / (area of the target) R reaction = N i σ (nAt)/A = N i σ nt
