Write on the alpha- ray scattering experiment.

When a silver foil (Z = 47) was used in an alpha ray scattering experiment , the number of alpha -particles scattered at 30^(@) was found to be 200 per minute. If the silver foil is replaced by alumninium (z = 13) foil of same thickness, the number of alpha -particles scattered per minute at 30^(@) is nearly equal to
