Nucleation kinetic factor.

Computes \(\beta = 4\pi \, (N_a / V_m)^{4/3} \, R_{\mathrm{crit}}^2 / \mathrm{sum}\), where \(R_{\mathrm{crit}}\) is the critical radius for nucleation, \(\mathrm{sum}\) is the projected diffusivity sum, \(V_m\) is the molar volume of the precipitate, and \(N_a\) is Avogadro’s number.
