Stellar reaction rate for (22)Mg + p -> (23)Al from the asymptotic normalization coefficient in the mirror nuclear system (22)Ne + n -> (23)Ne
(American Physical Society, 2010)
The production of (22)Na in ONe novae can be influenced by the (22)Mg(p,gamma)(23)Al reaction. To investigate this reaction rate at stellar energies, we have determined the asymptotic normalization coefficient (ANC) for ...
Astrophysical S factor for Be-9(p,gamma)B-10
(American Physical Society, 1999)
The Be-9(p, gamma) B-10 reaction plays an important role in primordial and stellar nucleosynthesis of light elements in the p shell, but the energy dependence of S(E) has not been well understood. We reanalyze the existing ...
Asymptotic normalization coefficients for C-13+p -> N-14
(American Physical Society, 1998)
The C-13(N-14,C-13)N-14 proton exchange reaction has been measured at an incident energy of 162 MeV. Angular distributions were obtained for proton transfer to the ground and low-lying excited states in N-14. Elastic ...
Measurements of phi meson production in relativistic heavy-ion collisions at the BNL Relativistic Heavy Ion Collider (RHIC)
(American Physical Society, 2009)
We present results for the measurement of phi meson production via its charged kaon decay channel phi -> K(+) K(-) Au + Au collisions at root S(NN) = 62.4, 130, and 200 GeV, and in p + p and d + Au collisions at v root ...
Neutral pion production in Au plus Au collisions at root s(NN)=200 GeV
(American Physical Society, 2009)
The results of midrapidity (0 < y < 0.8) neutral pion spectra over an extended transverse momentum range (1 < p(T) < 12 GeV/c) in root s(NN) = 200 GeV Au + Au collisions, measured by the STAR experiment, are presented. The ...
Production of e(+)e(-) pairs accompanied by nuclear dissociation in ultraperipheral heavy-ion collisions
(American Physical Society, 2004)
We present data on e(+)e(-) pair production accompanied by nuclear breakup in ultraperipheral gold-gold collisions at a center of mass energy of 200 GeV per nucleon pair. The nuclear breakup requirement selects events at ...
l-forbidden Gamow-Teller beta decay of Cu-57
(American Physical Society, 1996)
Absolute branching ratios for the beta decay of Cu-57 to excited states up to 3.3 MeV in Ni-57 have been determined, including the rho-forbidden Gamow-Teller transition to the first excited state in Ni-57. Four transitions ...
Gamow-Teller strength of Mg-26
(American Physical Society, 1996)
We have measured cross sections for (d,He-2)-induced reactions on Mg-26 at an energy of E(d)=125.2 MeV. The measured Gamow-Teller strength is significantly smaller than that inferred from (p,n) reactions. We demonstrate ...
Low-lying levels in Cu-57 and the rp process
(American Physical Society, 1996)
The level scheme of Cu-57 is investigated via the H-1(Ni-58,Cu-57-gamma)2n reaction by using the recoil mass spectrometer MARS at the Texas AandM Cyclotron Institute. Three low-lying excited states are observed in Cu-57 ...
Tests of transfer reaction determinations of astrophysical S factors
(American Physical Society, 1999)
The O-16(He-3,d)F-17 reaction has been used to determine asymptotic normalization coefficients for transitions to the ground and first excited states of F-17. Th, coefficients provide the normalization for the tails of the ...
