We are asked to calculate the reaction cross-section ( \sigma ) for a proton-induced reaction on a thin ( ^7_3\text{Li} ) target. We’ll solve step by step manually. Given data: * Target thickness: ( t = 0.01 , \text{mm} = 0.01 \times 10^{-3} , \text{m} = 1 \times 10^{-5} , \text{m} ) * Neutron yield: ( N_n = 10^9 , \text{s}^{-1} ) * Lithium density: ( \rho = 500 , \text{kg/m}^3 ) * Lithium atomic mass: ( A = 7 , \text{u} = 7 \times 1.66 \times 10^{-27} , \text{kg} = 1.162 \times 10^{-26} , \text{kg} ) * Proton
