Nuclear Surface Effects

The surface of the nucleus is treated by a phenomenological and self-consistent statistical method, neglecting Coulomb effects, in an attempt to correlate such nuclear properties as the volume energy, surface energy, falloff distance, and mean radius. Assuming a value of ∼3.3×${10}^{-13\mathrm{}}$ cm for the surface thickness we estimate the nuclear compressibility to be of the order of $125A+210A^{\frac{2}{3}}$ Mev. A thinner nuclear surface (the experimental value is 2.5×${10}^{-13\mathrm{}}$ cm) would lead to larger values for the compressibility and conversely. The nuclear potential is found to extend ∼0.7×${10}^{-13\mathrm{}}$ cm further in radius than the nuclear density.
