Giant monopole resonance strength in Ca-40
(American Physical Society, 1997)
The giant resonance region in Ca-40 was studied with inelastic scattering of 240 MeV alpha particles at small angles including 0 degrees. A peak at E-x = 17.5 +/- 0.4 MeV with Gamma = 4.95 +/- 0.25 MeV was found to contain ...
Hadron production from quark coalescence and jet fragmentation
(American Physical Society, 2005)
Transverse momentum spectra of pions, protons, and antiprotons in Au+Au collisions at intermediate RHIC energy root s(NN)=62 GeV are studied in a model that includes both quark coalescence from the dense partonic matter ...
Specific-heat discontinuity in impure two-band superconductors
(American Physical Society, 2003)
The Ginzburg-Landau coefficients and the jump of the specific heat are calculated for a disordered two-band superconductor. We start with the analysis of a more general case with arbitrary anisotropy. While the specific-heat ...
Isoscalar electric multipole strength in C-12
(American Physical Society, 2003)
The excitation region in C-12 below E-x=45 MeV was studied using 240 MeV alpha-particle scattering. Elastic scattering was measured from theta(c.m.)=3.8degrees to 49.4degrees and density dependant folding optical model ...
Thermalization of heavy quarks in the quark-gluon plasma
(American Physical Society, 2005)
Charm- and bottom-quark rescattering in a quark-gluon plasma (QGP) is investigated with the objective of assessing the approach toward thermalization. Employing a Fokker-Planck equation to approximate the collision integral ...
The N-14(Be-7,B-8)C-13 reaction and the Be-7(p,gamma)B-8 S factor
(American Physical Society, 1999)
The N-14(Be-7,B-8)C-13 reaction was studied using an 85 MeV Be-7 radioactive beam. The asymptotic normalization coefficients for the virtual transitions Be-7+pB-8 were determined from the measured cross section. These ...
Multiplicity and pseudorapidity distributions of charged particles and photons at forward pseudorapidity in Au plus Au collisons at root s(NN)=62.4 GeV
(American Physical Society, 2006)
We present the centrality-dependent measurement of multiplicity and pseudorapidity distributions of charged particles and photons in Au+Au collisions at root s(NN)=62.4 GeV. The charged particles and photons are measured ...
Cross section for charmonium absorption by nucleons
(American Physical Society, 2002)
The cross section for J/psi absorption by nucleons is studied using a gauged SU(4) hadronic Lagrangian but with empirical particle masses, which has been used previously to study the cross sections for J/psi absorption by ...
Asymptotic normalization coefficients and the Be-7(p, gamma)B-8 astrophysical S factor
(American Physical Society, 2001)
We consider the results of two proton transfer reactions, B-10(Be-7, B-8)Be-9 and N-14(Be-7, B-8)C-13, to obtain a weighted average of the measured asymptotic normalization coefficients for the virtual transition 7Be +pB-8. ...
J/Psi suppression in ultrarelativistic nuclear collisions
(American Physical Society, 2000)
Using a multiphase transport model, we study the relative importance of J/psi suppression mechanisms due to plasma screening, gluon scattering, and hadron absorption in heavy ion collisions at the Relativistic Heavy Ion ...
