Quenching Collisions of Low-Energy Metastable Multiply-Charged Argon Ions
(American Physical Society, 1994)
Quenching rates have been measured for selected metastable levels of Ar(q+) ions (q = 2, 3, 9, and 10) stored in a Kingdon ion trap, with mean energies of 262q eV and 181q eV. Effective quenching cross sections derived ...
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 ...
Probing the softest region of the nuclear equation of state
(American Physical Society, 1998)
An attractive, energy-dependent mean-field potential for baryons is introduced in order to generate a soft region in the nuclear equation of state, as suggested by recent lattice QCD calculations of baryon-free matter at ...
Tests of transfer reaction determinations of astrophysical S factors
(American Physical Society, 1999)
The O-16(He-3,d)F-17 reaction has been used to determine asymptotic normalization coefficients for transitions to the ground and first excited states of F-17. Th, coefficients provide the normalization for the tails of the ...
K+ production in baryon-baryon and heavy-ion collisions
(American Physical Society, 1998)
Kaon production cross sections in nucleon-nucleon, nucleon-Delta, and Delta-Delta interactions are studied in a boson exchange model. For the latter two interactions, the exchanged pion can be on-mass shell
Medium Effects on Kaon and Antikaon Spectra in Heavy-Ion Collisions
(American Physical Society, 1993)
In the linear chiral perturbation theory, both kaon and antikaon masses decrease in dense matter. There is also a repulsive vector potential for the kaon and an attractive one for the antikaon. With these effects included ...
