Please prove that in homogeneous nucleation of solidificationthe critical radius and activation energy are ??? = (? 2??????) ( 1) and ???? = (16????3????2 ) 1 , respectively, ????? ??? 3?????2???2 in which ? is the surface free energy, Tm is the meltingtemperature, ?T is the degree of supercooling (Tm - T), and ?Hf isthe latent heat of fusion.
