Zeldovich factor for nucleation.

Computes \(Z = \dfrac{V_m}{2\pi N_a R_{\mathrm{crit}}^2} \sqrt{\dfrac{\gamma}{k T}}\), where \(R_{\mathrm{crit}}\) is the critical radius for nucleation, \(\gamma\) is the surface energy of the precipitate, \(T\) is the temperature, \(V_m\) is the molar volume, \(N_a\) is Avogadro’s number, and \(k\) is the Boltzmann constant.
