This installment of computing prescriptions illustrates how complex arithmetic can simplify algorithms in two-dimensional Cartesian vector space as well as how to make difficult numerical integrals tractable. In other words, computer languages for sc

Solutions of the Schrodinger equation that pertain to different energies are orthogonal by virtue of quantum dynamics. However, when we obtain such solutions numerically using library differential equation solvers, and when the inner product is defin

As we attempt more sophisticated projects in science and engineering, the mathematical tools we apply to them also become more sophisticated. Because so few problems lend themselves to closed-form solution, we often need to convert formal definitions

The phenomenological relativistic theory of nuclear single-particle dynamics is reviewed and its salient characteristics discussed. The phenomenological (relativistic) potential strengths necessary to secure agreement with the usual low-energy proper

The analogy between the QCD vacuum - supposed to be a colour-magnetic superconductor - and the superconducting state, is exploited to estimate the reduction in average string tension experienced by hadrons in nuclei. This reduction leads to larger ra

The Chou-Yang model of the elastic profile function for high-energy collisions is modified to take into account the possibility that the projectile, the target, or both, are deformed from sphericity. Simple expressions for the elastic amplitudes and

Experimental data on high-energy inclusive inelastic electron- 4 He scattering are studied in terms of previously known electron-nucleon scattering data using the impulse approximation. Impressive agreement is obtained except on either side of the qu

The pionic stripping model of ( p , π + ) is used to derive predictions of polarization effects, including (polarized proton) + (unpolarized everything else) right-left asymmetries, stripping to partially filled shells, and selected (polarized beam)
