We present a parametrization and two fits to proton nucleus scattering data from 20 to 1040 MeV and mass ranges from $^{4}\mathrm{He}$ to $^{208}\mathrm{Pb}$. We show that $^{4}\mathrm{He}$ can be included with the other nuclei instead of having to b

We present global Dirac optical model fits to elastic proton scattering data from heavy nuclear targets at energies between 65 and 1040 MeV. Such optical potentials provide critical input for a wide variety of nuclear reactions. The energy and mass n

Comparisons are made between results of calculations for intermediate energy nucleon-nucleus scattering for 12C, 16O, 40Ca, 90Zr, and 208Pb, using optical potentials obtained from global Dirac phenomenology and from a microscopic Schr\"odinger model.

We derive a stability condition for the Thomas-Fermi solution of a finite nucleus where the underlying force has a finite range. The stability condition can be cast in the form of an eigenvalue equation; these eigenvalues must be all positive. The lo

The diffusivity of the nuclear surface plays an important role in peripherial collisions between two heavy ions. We show that a finite range force produces a diffuse surface for static nuclei in the Vlasov prescription. The surface is calculated self

Differential cross sections for proton elastic scattering from $^{42}$,44,48Ca have been measured at seven energies in the laboratory energy range from 21.0 to 48.4 MeV, and for $^{40}\mathrm{Ca}$ at six energies between 25.0 and 45.0 MeV. Measuremen

A new way of dealing with the unwanted high momentum components in low energy pion-nucleus optical potentials is presented. The method is developed strictly in accordance with a principle of “smoothness” which has been found very helpful in other

Presented here is an algorithm tailored to solve the radial Schrodinger equation for the case of proton scattering from an optical potential. The algorithm is straightforward to use and results in a significant increase in speed, around a factor of 2

The amplitude for the ( p,..pi../sup +/) reaction is calculated in a relativistic one-nucleon model with use of a distorted-wave Born-approximation approach. The nucleon continuum and bound-state wave functions are solutions of Dirac equations with a
