Q. 6. a- particles from a polonium source strike a thin gold foil of thickness 4 x 10-7 m. Most of the particles scatter in the forward direction but (1/6-17 x 106) fraction of a particles are found to be scattered by more than 90°. Find the cross-section of this type scattering if the number of gold nuclei per unit volume is 5.9 x 1028 per meter.
