Measurement of proton proton elastic scattering in pure initial spin states at 11.75 GeV/c
(Elsevier, 1976-07-19)
The elastic cross section for proton proton scattering at 11.75 GeV/c was measured at the Argonne ZGS using a 50% polarized target. In the range p[perpendicular]2=0.6 --> 2.2 (GeV/c)2 we obtained precise measurements ...
Measurement of the vacuum decay rate of orthopositronium formed in an MgO-lined cavity
(Elsevier, 1978-11-27)
Orthopositronium decay rates are measured in MgO-lined cavities with various volumes and entrance apertures. Systematic effects of the entrance aperture, cavity geometry, and collisional pick-off are measured. The vacuum ...
Some properties of nearly premixed laminar flame propagation along weakly stratified layers in combustible gas mixtures
(Elsevier, 1990-02)
Nearly premixed laminar flame propagation along weakly stratified layers in combustible gas mixtures is examined theoretically in the limit of weak flame stretch, high activation energy, and unity Lewis number. The ...
Neutron-deuteron elastic scattering from 6 to 12.5 GeV/c
(Elsevier, 1976-03-01)
The differential cross section for neutron-deuteron elastic scattering was measured for four-momentum transfers 0.3 t 2 with incident neutron momenta between 6 and 12.5 GeV/c. The measurement was made with spark chambers ...
Spin-polarized low-energy positron beams and their applications
(Springer-Verlag, 1987-08)
The production and use of low-energy (100 eV to 5 keV) high-intensity, spin-polarized positron beams is reviewed. Methods for obtaining beams with high polarization are discussed. Applications include studies of the ...
A posteriori image-correcting "deconvolution" by holographic fourier-transform division
(Elsevier, 1967-07-31)
Division of spatial field distributions in the Fourier-transform domain for "resolution-retrieving", "corrective" image deconvolution of the "smearing" resulting from extended "instrument functions" in optical imaging, ...
Deposition and Properties of Superconducting MgB 2 Thin Films
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2003-10)
The recently discovered superconductor MgB 2 with T c at 39 K has great potential in superconducting electronics. In this paper, we review the deposition techniques used for MgB 2 thin films in the light of a thermodynamic ...
Growth and properties of quasiperiodic heterostructures
(Elsevier, 1987-02-02)
We have recently demonstrated the MBE growth of heterostructures in which layers of GaAs and AlAs were deposited in a Fibonacci sequence. This yields a quasiperiodic structure with the ratio of incommensurate periods equal ...
Electric field effects on intersubband transitions in quantum well structures
(Elsevier, 1987)
We report on a Raman scattering study of the electric-field dependence of c0 --> c1 intersubband transitions of electrons in a 264 A GaAs- Al0.3Ga0.7As quantum-well structure. The measured Stark shifts are in very good ...
