Higher-order effects on the incompressibility of isospin asymmetric nuclear matter
(American Physical Society, 2009)
Analytical expressions for the saturation density of asymmetric nuclear matter as well as its binding energy and incompressibility at saturation density are given up to fourth order in the isospin asymmetry delta=(rho(n) ...
Refractive effects in the scattering of loosely bound nuclei
(American Physical Society, 2004)
A study of the interaction of the loosely bound nuclei Li-6,Li-7 at 9 and 19 MeV/nucleon with light targets has been undertaken. With the determination of unambiguous optical potentials in mind, elastic data for four ...
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 ...
Precise measurement of alpha(K) for the M4 transition from Ir-193(m): A test of internal-conversion theory
(American Physical Society, 2004)
The 10.5-day isomer in Ir-193 decays by a single 80.2-keV M4 transition directly to the ground state of that nucleus. We have measured the total intensity of K x rays relative to 80.2-keV gamma rays for this transition to ...
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 ...
Test of internal-conversion theory with measurements in Cs-134 and Ba-137
(American Physical Society, 2007)
We have measured the ratio of K-shell internal conversion coefficients, alpha(K), for the 127.5-keV E3 transition in Cs-134 and the 661.7-keV M4 transition in Ba-137. Previous measurements of these alpha(K) values led to ...
Isoscalar giant resonance strength in Si-28
(American Physical Society, 2007)
Data taken previously covering the giant resonance region from 9 MeV < E-x < 42 MeV in Si-28 with inelastic scattering of 240 MeV alpha particles at small angles including 0(degrees) have been reanalyzed. Treating all of ...
Pion interferometry in Au plus Au and Cu plus Cu collisions at s(NN)=62.4 and 200 GeV
(American Physical Society, 2009)
We present a systematic analysis of two-pion interferometry in Au+Au collisions at s(NN)=62.4 GeV and Cu+Cu collisions at s(NN)=62.4 and 200 GeV using the STAR detector at the Relativistic Heavy Ion Collider (RHIC). The ...
Isospin-dependent properties of asymmetric nuclear matter in relativistic mean field models RID A-2398-2009
(American Physical Society, 2007)
Using various relativistic mean-field models, including nonlinear ones with meson field self-interactions, models with density-dependent meson-nucleon couplings, and point-coupling models without meson fields, we have ...
Beta decay of proton-rich nucleus Al-23 and astrophysical consequences
(American Physical Society, 2006)
We present the first study of the beta decay of Al-23 undertaken with pure samples. The study was motivated by nuclear astrophysics questions. Pure samples of Al-23 were obtained from the momentum achromat recoil separator ...
