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 ...
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 ...
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 ...
