3d-3p transitions in (. mu. /sup -/He/sup 4/)/sup +/
An experiment to measure the energy of 3d-3p transitions in the (..mu../sup -/He/sup 4/)/sup +/ ion is now in progress. The experiment, which is being performed at the Brookhaven National Laboratory Alternating Gradient Synchrotron, will use an infrared CO/sub 2/ laser to stimulate the transitions. These transitions are of interest because their energy is due almost entirely to the polarization of the vacuum. In a pure Coulomb field, states with the same principal quantum number, n, and total angular momentum, J, are degenerate. Vacuum polarization, because of its nonlinear dependence on electric field strength, results in departure from an inverse square Coulomb field, causing a splitting which depends on the orbital angular momentum, removing the degeneracy. The dominance of vacuum polarization in giving rise to these splittings in the muonic ion is in contrast to the situation in electronic atoms where vacuum polarization makes a very minor contribution to the Lamb shift. 4 refs., 4 figs.

Accelerated beam experiments with the ORNL SITEX (Surface Ionization with Transverse Extraction) and VITEX (Volume Ionization with Transverse Extraction) H/sup -//D/sup -/ sources
Beam parameters have been measured for both the Surface Ionization with Transverse Extraction (SITEX) and Volume Ionization with Transverse Extraction (VITEX) H/sup -//D/sup -/ ion sources. Both sources use a reflex discharge to generate the main plasma. Beam energies up to 18 keV were used for pulse lengths up to several seconds. For SITEX, Faraday cup magnetically analyzed D/sup -/ beam currents of 110 mA at extraction densities of 48 mA/cm/sup 2/ and at a source ion temperature of 4 eV have been measured. For the VITEX results, Faraday cup magnetically analyzed beam currents of up to 80 mA at extraction densities of 27 mA/cm/sup 2/ and at a source ion temperature of 0.5 eV have been measured. Virtually all extracted electrons were recovered at an energy of 10 to 30% of the accel beam energy, and there were none in the analyzed beam.

Acceleration of electrons by the wake field of proton bunches
This paper discusses a novel idea to accelerate low-intensity bunches of electrons (or positrons) by the wake field of intense proton bunches travelling along the axis of a cylindrical rf structure. Accelerating gradients in excess of 100 MeV/m and large ''transformer ratios'', which allow for acceleration of electrons to energies in the TeV range, are calculated. A possible application of the method is an electron-positron linear collider with luminosity of 10/sup 33/ cm/sup -2/ s/sup -1/. The relatively low cost and power consumption of the method is emphasized.

The acceptance of the SSC (Superconducting Supercollider) clustered lattice
The physical apertures of all elements of the SSC storage lattices are considered to determine whether correction of random multipole fields in the triplet quadrupoles is necessary when betatron amplitudes there are no more than the inner radius of the beam pipe. During computer simulated beam tracking the influence of random multiple fields was included as a kick given to the test particle at the center of each quadrupole and at the ends of every dipole. The degree of multipole correction needed is shown. (LEW)

Accuracy of Nodal Transport and Simplified-P3 Fluxes in Benchmark Tests
Here we summarize recent work exploring the accuracy of fluxes computed, both by nodal transport methods, and by the simplified-spherical harmonics (SP/sub l/) method. Apparently, significant errors in nodal transport fluxes were first noted by Wagner et al., and attributed to the isotopic-transverse-leakage (ITL) approximation. Later Lawrence detected substantial errors, due to the ITL approximation, in his nodal transport (NTT) solution of the IAEA Stepanek benchmark problem. Gelbard concluded on theoretical grounds that nodal transport fluxes, computed in XY geometry using ITL, should be much more accurate on the coordinate axes than halfway between them and that, at 45/sup 0/ from the axes, nodal transport methods using ITL should give only about half of the true transport correction.

Accurate interatomic potentials for Ni, Al and Ni/sub 3/Al
To obtain meaningful results from atomistic simulations of materials, the interatomic potentials must be capable of reproducing the thermodynamic properties of the system of interest. Pairwise potentials have known deficiencies that make them unsuitable for quantitative investigations of defective regions such as crack tips and free surfaces. Daw and Baskes (Phys. Rev. B 29, 6443 (1984)) have shown that including a local ''volume'' term for each atom gives the necessary many-body character without the severe computational dependence of explicit n-body potential terms. Using a similar approach, we have fit an interatomic potential to the Ni/sub 3/Al alloy system. This potential can treat diatomic Ni/sub 2/, diatomic Al/sub 2/, fcc Ni, fcc Al and L1/sub 2/ Ni/sub 3/Al on an equal footing. Details of the fitting procedure are presented, along with the calculation of some properties not included in the fit.
