The differential cross section for scattering 6.5-mev alpha particles at 120° off a silver nucleus is about 0.5 barns/sr. if a total of 10 10 alphas impinge on a silver foil of thickness 1 itm and if we detect the scattered particles using a counter of area 0.1 mm 2 at 120° and 1 cm from the target, about how many scattered alphas should we expect to count? (silver has a specific gravity of 10.5, and atomic mass of 108.) 14.12 ***
