    • Astrophysical S(E) factor of the (15)N(p, alpha)(12)C reaction at sub-Coulomb energies via the Trojan horse method 

      La Cognata, M.; Romano, S.; Spitaleri, C.; Cherubini, S.; Crucilla, V.; Gulino, M.; Lamia, L.; Pizzone, R. G.; Tumino, A.; Tribble, Robert E.; Fu, Changbo; Goldberg, V. Z.; Mukhamedzhanov, A. M.; Schmidt, D.; Tabacaru, G.; Trache, L.; Irgaziev, B. F. (American Physical Society, 2007)
      The low-energy bare-nucleus cross section for (15)N(p, alpha)(12)C is extracted by means of the Trojan horse method applied to the (2)H((15)N,alpha(12)C)n reaction at E(beam) = 60 MeV. For the first time we applied the ...
    • (D,he-2) Reactions at E(d)=125.2 Mev 

      Xu, HM; Ajupova, G. K.; Betker, A. C.; Gagliardi, Carl A.; Kokenge, B.; Lui, YW; Zaruba, A. F. (American Physical Society, 1995)
      We have measured cross sections for (d, He-2) induced reactions on the p-shell nuclei Li-6, C-12, and C-13 and the sd-shell nucleus Mg-24 at an energy of E(d)=125.2 MeV. The measured excitation energy spectra are very ...
    • Deuteron production and elliptic flow in relativistic heavy ion collisions 

      Oh, Yongseok; Lin, Zi-Wei; Ko, Che Ming. (American Physical Society, 2009)
      The hadronic transport model ART is extended to include the production and annihilation of deuterons via the reactions BB dM, where B and M stand for baryons and mesons, respectively, as well as their elastic scattering ...
    • Electron capture from H-2 to highly charged Th and Xe ions trapped at center-of-mass energies near 6 eV 

      Weinberg, G.; Beck, B. R.; Steiger, J.; Church, David A.; McDonald, J.; Schneider, D. (American Physical Society, 1998)
      Ions with charge states as high as 80+, produced in the Lawrence Livermore National Laboratory electron beam ion trap were extracted and transferred to a Penning ion trap (RETRAP). RETRAP was operated at cryogenic temperature ...
    • Elliptic flow of deuterons in relativistic heavy-ion collisions 

      Oh, Yongseok; Ko, Che Ming. (American Physical Society, 2007)
      Using a dynamical model based on the NN -> d pi,NNN -> dN, and NN pi -> d pi reactions and measured proton and pion transverse momentum spectra and elliptic flows, we study the production of deuterons and their elliptic ...
    • Forward Angle Analyzing Power in (P)over-Right-Arrow-N and (P)over-Right-Arrow-P Quasi-Free Scattering at 643 and 797 Mev 

      Glass, G.; Bhatia, T. S.; Hiebert, John C.; Kenefick, R. A.; Nath, S.; Northcliffe, L. C.; Tippens, W. B.; Simmons, J. E. (American Physical Society, 1993)
      Polarized proton beams and a liquid-deuterium target were used to measure the analyzing power for quasifree p-n over arrow pointing right and p-p over arrow pointing right scattering in the forward direction at 643 and 797 ...
    • Gamow-Teller strength of Mg-26 

      Xu, HM; Gagliardi, Carl A.; Ajupova, G. K.; Kokenge, B.; Lui, YW. (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 ...
    • Giant monopole strength in Ni-58 

      Lui, YW; Clark, HL; Youngblood, David H. (American Physical Society, 2000)
      The strength distribution of the giant monopole resonance in Ni-58 has been measured from E-x = 10 to 35 MeV using small-angle scattering of 240-MeV alpha particles. E0 strength corresponding to 74(-12)(+22)% of the E0 ...
    • J/psi absorption by nucleons in the meson-exchange model 

      Oh, Yongseok; Liu, Wei; Ko, Che Ming. (American Physical Society, 2007)
      We reinvestigate the J/Psi dissociation processes induced by the reactions with nucleons, J/Psi + N -> D-(*) + Lambda(c), in the meson- exchange model. Main constraints used in this work are vector- meson dominance and ...
    • Light clusters production as a probe to nuclear symmetry energy RID A-2398-2009 

      Chen, LW; Ko, Che Ming; Li, Ba. (American Physical Society, 2003)
      Using an isospin-dependent transport model for heavy-ion collisions induced by neutron-rich nuclei at intermediate energies, we study the production of light clusters such as deuteron, triton, and He-3 via coalescence of ...
    • Quenching Collisions of Low-Energy Metastable Multiply-Charged Argon Ions 

      Church, David A.; Yang, L. S.; Tu, S. G. (American Physical Society, 1994)
      Quenching rates have been measured for selected metastable levels of Ar(q+) ions (q = 2, 3, 9, and 10) stored in a Kingdon ion trap, with mean energies of 262q eV and 181q eV. Effective quenching cross sections derived ...
