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. ...
Compensation of ac Stark shifts in optical magnetometry RID B-9041-2008 RID A-1272-2007
(American Physical Society, 2001)
The ac Stark shift of the resonance frequency of the nonlinear magneto-optic effect (NMOE) results in a fundamental broadening of this resonance which limits the precision of optical magnetometry based on NMOE. We have ...
Strangeness equilibration in heavy ion collisions
(American Physical Society, 2001)
Using a relativistic transport model for heavy ion collisions at energies that Lire below the threshold for kaon and antikaon production in nucleon-nucleon collisions, we study how their abundances approach the canonical ...
Spin glass behavior in FeAl2
(American Physical Society, 2001)
Magnetic and transport measurements indicate FeAl2 to be an ordered intermetallic spin glass, with canonical behavior including a susceptibility cusp at T-f = 35 K and frequency-dependent susceptibility below T-f. The ...
Charged particle rapidity distributions at relativistic energies
(American Physical Society, 2001)
Using a multiphase transport model (AMPT), which includes both initial partonic and final hadronic interactions, we study the rapidity distributions of charged particles such as protons, antiprotons, pions, and kaons in ...
Fourth-order diffusion Monte Carlo algorithms for solving quantum many-body problems
(American Physical Society, 2001)
By decomposing the important sampled imaginary time Schrodinger evolution operator to fourth order with positive coefficients, we derived a number of distinct fourth-order diffusion Monte Carlo algorithms. These sophisticated ...
Response of C(60) and C(n) to ultrashort laser pulses
(American Physical Society, 2001)
In this paper we introduce a method for realistic simulations of nonadiabatic processes, including the interaction of light with matter. Calculations of the response Of C(60) and carbon chains to laser pulses demonstrate ...
Isoscalar giant dipole resonance in Zr-90, Sn-116, and Pb-208
(American Physical Society, 2001)
Strength functions for isoscalar dipole excitations in Zr-90, Sn-116, and Pb-208 have been measured with inelastic scattering of 240 MeV alpha particles at small angles. The isoscalar E1 strength distribution in each nucleus ...
Asymptotic normalization coefficients, spectroscopic factors, and direct radiative capture rates
(American Physical Society, 2001)
We compare the use of asymptotic normalization coefficients (ANC's) and spectroscopic factors determined from peripheral transfer reactions for determining the overall normalization of peripheral direct radiative capture ...
Giant resonances in O-16
(American Physical Society, 2001)
Giant resonances in O-16 have been studied with inelastic scattering of 240 MeV alpha particles at small angles, Isoscalar E0, E1, and E2 strength corresponding to 48 +/- 10%, 32 +/- 7%, and 53 +/- 10%, of the respective ...
