Liquid Drop Model

Liquid Drop model First proposed by N-Bohr $ F. Kalckar in 1937. Later applied by CF Van weizsacker and H.A Bethe to develop Bethe Weizsacker Semi emperical formula for Binding energy ($ Mass) of the nucleus Emperical Experimentally observed seme used assumption, approximation to Simplifier calculation.
