Isoscalar giant resonances in (48)Ca
(American Physical Society, 2011)
The giant resonance region from 9.5 MeV < E(x) < 40 MeV in (48)Ca has been studied with inelastic scattering of 240-MeV alpha particles at small angles, including 0 degrees. 95(-15)(+11)% of E0 energy-weighted sum rule ...
Strange and multistrange particle production in Au plus Au collisions at root s(NN)=62.4 GeV
(American Physical Society, 2011)
We present results on strange and multistrange particle production in Au + Au collisions at root s(NN) = 62.4 GeV as measured with the STAR detector at RHIC. Midrapidity transverse momentum spectra and integrated yields ...
Measurement of the half-life of (198)Au in a nonmetal: High-precision measurement shows no host-material dependence
(American Physical Society, 2010)
We have measured the half-life of the beta(-) decay of (198)Au to be 2.6948(9)d, with the nuclide sited in an insulating environment. Comparing this result with the half-life we measured previously with a metallic environment, ...
Elastic and inelastic scattering to low-lying states of (58)Ni and (90)Zr using 240-MeV (6)Li
(American Physical Society, 2010)
Elastic and inelastic scattering of 240-MeV (6)Li particles from (58)Ni and (90)Zr were measured with the multipole-dipole-multipole spectrometer from 4 degrees <= theta(c.m.) <= 43 degrees. The elastic scattering data ...
Precise half-life measurement of the superallowed beta(+) emitter (26)Si
(American Physical Society, 2010)
We measured the half-life of the superallowed 0(+) -> 0(+) beta(+) emitter (26)Si to be 2245.3(7) ms. We used pure sources of (26)Si and employed a high-efficiency gas counter, whichwas sensitive to positrons from both ...
Pion femtoscopy in p plus p collisions at root s=200 GeV
(American Physical Society, 2011)
The STAR Collaboration at the BNL Relativistic Heavy Ion Collider has measured two-pion correlation functions from p + p collisions at root s = 200 GeV. Spatial scales are extracted via a femtoscopic analysis of the ...
Medium modifications of the rho meson in nuclear photoproduction
(American Physical Society, 2010)
We extend our recent study of dilepton invariant-mass spectra from the decays of rho mesons produced by photon reactions off nuclei. We specifically focus on experimental spectra as recently measured by the CLAS Collaboration ...
Structure of (23)Al from the one-proton breakup reaction and astrophysical implications
(American Physical Society, 2011)
The ground state of the proton-rich nucleus (23)Al has been studied by one-proton removal on a carbon target at about 50 MeV/nucleon using the EXOGAM + SPEG experimental setup at GANIL. Longitudinal momentum distributions ...
Cooperative recombination of electron-hole pairs in semiconductor quantum wells under quantizing magnetic fields
(American Physical Society, 2010)
We present results of detailed investigations of light emission from semiconductor multiple quantum wells at low temperatures and high magnetic fields excited by intense femtosecond laser pulses. The intensity and linewidth ...
