np elastic spin-transfer measurements at 485 and 635 MeV
(American Physical Society, 1992)
We have measured the spin-transfer parameters K(LL), K(SL), K(LS) and K(SS) at 635 MeV from 50-degrees to 178-degrees c.m. and at 485 MeV from 74-degrees to 176-degrees c.m. These new data have a significant impact on the ...
Analyzing Power Measurement for Forward Angle N-P Scattering at 790 Mev

Giant Quadrupole-Resonance in Ni Isotopes
(American Physical Society, 1992)
Inelastic scattering of 129 MeV alpha particles has been used to excite the giant quadrupole resonance in Ni-58, Ni-60, Ni-62, Ni-64. The resonance was found to exhaust 58 +/- 12%, 76 +/- 14%, 78 +/- 14%, and 90 +/-16% of ...
Probing the softest region of the nuclear equation of state
(American Physical Society, 1998)
An attractive, energy-dependent mean-field potential for baryons is introduced in order to generate a soft region in the nuclear equation of state, as suggested by recent lattice QCD calculations of baryon-free matter at ...
Antilambda Enhancement in Ultrarelativistic Heavy-Ion Collisions
(American Physical Society, 1992)
In the Walecka model, the antilambda mass in dense nuclear matter is smaller than its value in free space. This reduces the threshold for antilambda production in dense matter that forms in the compression stage of ...
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 ...
np-elastic analyzing power An0 and spin transfer Knn
(American Physical Society, 1993)
We have measured the analyzing power A(NO) and the spin transfer K(NN) for np-elastic scattering from about 60-degrees to 170-degrees c.m. at 485, 635, and 788 MeV. The new data clarify previous discrepancies and complete ...
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 ...
