Isoscalar giant resonance strength in (24)Mg
(American Physical Society, 2009)
The giant resonance region from 9 MeV < E(x)< 60 MeV in (24)Mg has been studied with inelastic scattering of 240-MeV alpha particles at small angles, including 0(degrees). Isoscalar E0, E1, E2, and E3 strength was identified ...
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. ...
Hadronic scattering of charmed mesons
(American Physical Society, 2000)
The scattering cross sections of charm mesons with hadrons such as the pion, rho meson, and nucleon are studied in an effective Lagrangian. In heavy ion collisions, rescattering of produced charm mesons by hadrons affects ...
Scattering of Be-7 and B-8 and the astrophysical S-17 factor
(American Physical Society, 2006)
Measurements of Be-7 scattering at 87 MeV on a melamine (C3N6H6) target and of B-8 at 95 MeV on C were performed. For Be-7 the angular range was extended over previous measurements and monitoring of the intensity of the ...
Charmonium mass in nuclear matter
(American Physical Society, 2003)
The mass shift of charmonium states in nuclear matter is studied in the perturbative QCD approach. The leading-order effect due to the change of gluon condensate in nuclear matter is evaluated using the leading-order QCD ...
Isoscalar E0 strength between 6 and 11 MeV in Ca-40
(American Physical Society, 2003)
The region from 6<E-x<11 MeV in Ca-40 has been studied with inelastic scattering of 240 MeV alpha particles at small angles including 0degrees . Strength corresponding to 3.2+/-1.0% of the isoscalar E0 sum rule was identified ...
Asymptotic normalization coefficients for 14N+p -> O-15 and the astrophysical S factor for N-14(p, gamma)O-15
(American Physical Society, 2003)
The N-14(p,gamma)O-15 reaction, which controls energy production in the CNO cycle, has contributions from both resonance and direct captures to the ground and excited states. The overall normalization of the direct captures ...
Internal conversion coefficients in (134)Cs, (137)Ba, and (139)La: A precise test of theory
(American Physical Society, 2008)
Recently we measured the ratio of K-shell internal conversion coefficients, alpha(K), for the 127.5-keV E3 transition in (134)Cs and the 661.7-keV M4 transition in (137)Ba. We here report a measurement of the 165.9-keV M1 ...
Half-life of the electron-capture decay of (97)Ru: Precision measurement shows no temperature dependence
(American Physical Society, 2009)
We have measured the half-life of the electron-capture (ec) decay of (97)Ru in a metallic environment, both at low temperature (19 K), and also at room temperature. We find the half-lives at both temperatures to be the ...
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 ...
