H-2(p,n)2p Spin Transfer from 305 to 788 Mev
(American Physical Society, 1992)
Measurements of the spin-transfer parameter K(LL) for H-2(p, n)2p at 0-degrees to calibrate the neutron-beam polarization clarify a normalization discrepancy affecting np data at LAMPF. The new data are in good agreement ...
Phi Meson in Dense Matter
(American Physical Society, 1992)
The effect of the kaon loop correction to the property of a phi meson in dense matter is studied in the vector dominance model. Using the density-dependent kaon effective mass determined from the linear chiral perturbation ...
Measurement of Spin-Correlation Parameters all and Asl in P-P Elastic-Scattering from 500 Mev to 800 Mev
(American Physical Society, 1992)
The spin-correlation observable A(LL) for p-p elastic scattering has been measured at energies 589, 640, 692, 743, and 793 MeV, over a c.m. angular range between 20-degrees and 100-degrees. The spin observable A(SL) was ...
Structure and Collective Excitations of He-4 Clusters
(American Physical Society, 1992)
We compute zero-temperature ground-state energies, one- and two-body densities, collective-excitation spectra, transition densities, and static and dynamic structure functions of He-4 clusters up to a cluster size of N = ...
Simple Heuristic Derivation of the Universal Jump in the Superfluid Density of 2-Dimensional Superfluids
(American Physical Society, 1992)
A simple heuristic derivation is given for the universal jump in the superfluid density rho(s) at the transition temperature T(c) of a two-dimensional superfluid. It is based on the mathematical equivalence of the Hamiltonians ...
Phase-Boundary of several Multicube Superconducting Circuits in a Magnetic-Field of Arbitrary Magnitude and Direction
(American Physical Society, 1992)
A previous study [C.-R. Hu and C.-H. Huang, Phys. Rev. B 43, 7718 (1991)] of the phase boundary T(c)(H) of a single-cube superconducting circuit in an external magnetic field H of arbitrary magnitude and direction is ...
np elastic spin-transfer measurements at 485 and 635 MeV
(American Physical Society, 1992)
We have measured the spin-transfer parameters K(LL), K(SL), K(LS) and K(SS) at 635 MeV from 50-degrees to 178-degrees c.m. and at 485 MeV from 74-degrees to 176-degrees c.m. These new data have a significant impact on the ...
Giant Quadrupole-Resonance in Ni Isotopes
(American Physical Society, 1992)
Inelastic scattering of 129 MeV alpha particles has been used to excite the giant quadrupole resonance in Ni-58, Ni-60, Ni-62, Ni-64. The resonance was found to exhaust 58 +/- 12%, 76 +/- 14%, 78 +/- 14%, and 90 +/-16% of ...
Antilambda Enhancement in Ultrarelativistic Heavy-Ion Collisions
(American Physical Society, 1992)
In the Walecka model, the antilambda mass in dense nuclear matter is smaller than its value in free space. This reduces the threshold for antilambda production in dense matter that forms in the compression stage of ...
Rho Meson in Dense Hadronic Matter
(American Physical Society, 1992)
The spectral function of a rho meson that is at rest in dense hadronic matter and couples strongly to the pion is studied in the vector dominance model by including the effect of the delta-hole polarization on the pion. ...
