A model potential for proton hydrates, in which the system is treated as a collection of rigid water monomers plus a lone proton, is used to investigate H+(H2O)n clusters for n near the magic number of 21. Various configurations which are local minim

Two empirical models are considered for the hydrates H+(H2O)n. In one, a rigid hydronium unit interacts with n−1 water molecules, and in another, a single proton with an effective hard‐core radius interacts with n waters. In each case, the polari

A planar four‐charge model for the water molecule, with a spherically symmetric Lennard‐Jones potential and a point polarizability, is examined. The model parameters are determined by fitting gas‐phase data for the one and two‐molecule system

Various relativistic treatments are applied to deuteron-nucleus elastic scattering at intermediate energies. There are various possibilities for spin-one wave equations. Here we have considered three of them, the Kemmer-Duffin-Petiau, Proca, and Wein

We perform a global analysis of intermediate energy nucleon plus /sup 208/Pb scattering data using the Dirac phenomenology. Proton elastic differential cross sections, analyzing powers, spin rotation functions, and total reaction cross sections, toge

We present results of calculations which suggest that several of the spin observables for elastic scattering of 500-MeV polarized protons from a polarized /sup 13/C target are sensitive to relativistic aspects of nuclear structure.

We present the first global relativistic optical-model treatment of proton-nucleus elastic scattering. Energy-dependent optical potential parameters for the Lorentz vector and scalar potentials of Dirac phenomenology are given. Several different assu

Lorentz scalar and four-vector optical potentials are obtained for protons elastically scattered from /sup 16/O, /sup 40/Ca, /sup 48/Ca, /sup 90/Zr, and /sup 208/Pb. It is demonstrated that Dirac optical potentials constrained by relativistic Hartree

We present a description of the spin-one Kemmer-Duffin-Petiau equations. An effective second-order equation is obtained for various types of interactions. An argument is given for the use of one particular form of interaction for deuteron-nucleus sca

We present a description of the spin-1 Kemmer-Duffin-Petiau equations and make an application to deuteron-nucleus scattering. Comparison with d${+}^{58}$Ni elastic scattering data at 400 MeV shows that the Kemmer-Duffin-Petiau model reproduces experi
