Isoscalar E0, E1, and E2 strength in Ca-40
(American Physical Society, 2001)
The giant resonance region from 10 particles at small angles including 0 degrees. Strength corresponding to 97 +/- 11%, 108 +/- 12%, and 62 + 10-20 % of the isoscalar E0, E2, and E1 sum rules, respectively, was identified ...
Finite-Hilbert-basis-set calculations for the angular distribution of ionized electrons produced in p+H impact at 20 keV
(American Physical Society, 2004)
We present a different method of extracting the angular distribution of ejected electrons in an ion-atom collision from a two-centered finite Hilbert basis-set calculation. We obtain good agreement with experiment for a ...
Asymptotic normalization coefficients for B-8 -> Be-7+p from a study of Li-8 -> Li-7+n
(American Physical Society, 2003)
Asymptotic normalization coefficients (ANCs) for Li-8-->Li-7+n have been extracted from the neutron transfer reaction C-13(Li-7,Li-8)C-12 at 63 MeV. These are related to the ANCs in B-8-->Be-7 + p using charge symmetry. ...
Analytical and micromagnetic study of a Neel domain wall
(American Physical Society, 2008)
For ferromagnets with exchange, dipolar interaction, and uniaxial anisotropy, by both analytic methods and micromagnetic simulations we study Neel domain walls in thin ferromagnetic strips of finite width. Comparison of ...
J/psi production in relativistic heavy ion collisions from a multiphase transport model
(American Physical Society, 2002)
Using a multiphase transport model, we study J/psi production from interactions between charm and anticharm quarks in the initial parton phase and between D and (D) over bar mesons in the final hadron phase of relativistic ...
Rapidity and species dependence of particle production at large transverse momentum for d+Au collisions at root S(NN)=200 GeV
(American Physical Society, 2007)
We determine rapidity asymmetry in the production of charged pions, protons, and antiprotons for large transverse momentum (p(T)) for d+Au collisions at root s(NN)=200 GeV. The rapidity asymmetry is defined as the ratio ...
Anisotropic flow in Cu plus Au collisions at root s(N N)=200GeV RID A-2398-2009
(American Physical Society, 2006)
The anisotropic flow of charged hadrons in asymmetric Cu+Au collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. Compared with previous results for symmetric Au+Au collisions, charged ...
Effects of geometry and impurities on quantum rings in magnetic fields RID D-3014-2009
(American Physical Society, 2006)
We investigate the effects of impurities and changing ring geometry on the energetics of quantum rings under different magnetic field strengths. We show that as the magnetic field and/or the electron number are/is increased, ...
Partonic effects on the elliptic flow at relativistic heavy ion collisions
(American Physical Society, 2002)
The elliptic flow in heavy ion collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. By converting the strings in the high energy density regions into partons, we find that the final ...
Nuclear modification factor of nonphotonic electrons in heavy-ion collisions, and the heavy-flavor baryon-to-meson ratio
(American Physical Society, 2009)
The nuclear modification factor R(AA) of nonphotonic electrons in Au + Au collisions at root(S)NN = 200 GeV is studied by considering the decays of heavy-flavor hadrons produced in a quark coalescence model. Although an ...
