In a Rutherford α-particle scattering experiment, identical α-particles having the same kinetic energy are incident separately on two thin metallic foils. The first foil has atomic number Z₁ = 30 and the second has atomic number Z₂ = 60. The foil thickness, target-atom number density, detector solid angle and scattering angle are identical. If the count rates are N₁ and N₂ respectively, what is N₂ ÷ N₁?
