    • 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 ...
    • Bound, virtual, and resonance S -matrix poles from the Schrödinger equation 
      Mukhamedzhanov, A. M.; Irgaziev, B. F.; Goldberg, V. Z.; Orlov, Yu. V.; Qazi, I. (Physical Review C - Nuclear Physics, 2010)
    • First observation of alpha-cluster states in the (14)O+(4)He interaction 
      Fu, Changbo; Goldberg, V. Z.; Rogachev, G. V.; Tabacaru, G.; Chubarian, G. G.; Skorodumov, B.; McCleskey, M.; Zhai, Y.; Al-Abdullah, T.; Trache, L.; Tribble, Robert E. (American Physical Society, 2008)
      We measured (14)O+(4)He excitation functions for elastic scattering which demonstrate, for the first time, a well developed alpha-cluster structure in the proton rich nucleus, (18)Ne. We present the excitation energies and ...
    • Improved determination of the astrophysical S(0) factor of the (15)N(p,alpha)(12)C reaction 
      La Cognata, M.; Goldberg, V. Z.; Mukhamedzhanov, A. M.; Spitaleri, C.; Tribble, Robert E. (American Physical Society, 2009)
      We present new improved R matrix fits of direct data and indirect Trojan Horse data for the (15)N(p,alpha)(12)C reaction and provide a more accurate recommended value of S(0)=73.0 +/- 5.0 MeV b from direct Redder data [A. ...
    • New astrophysical S factor for the (15)N(p,gamma)(16)O reaction via the asymptotic normalization coefficient (ANC) method 
      Mukhamedzhanov, A. M.; Bem, P.; Burjan, V.; Gagliardi, Carl A.; Goldberg, V. Z.; Hons, Z.; La Cognata, M.; Kroha, V.; Mrazek, J.; Novak, J.; Piskor, S.; Pizzone, R. G.; Plunkett, A.; Romano, S.; Simeckova, E.; Spitaleri, C.; Trache, L.; Tribble, Robert E.; Vesely, F.; Vincour, J. (American Physical Society, 2008)
      The (15)N(p,gamma)(16)O reaction provides a path from the CN cycle to the CNO bi-cycle and CNO tri-cycle. The measured astrophysical factor for this reaction is dominated by resonant capture through two strong J(pi) = 1(-) ...
    • Single and double proton emissions from the O-14+He-4 interaction 
      Fu, Changbo; Goldberg, V. Z.; Mukhamedzhanov, A. M.; Chubarian, G. G.; Rogachev, G. V.; Skorodumov, B.; McCleskey, M.; Zhai, Y.; Al-Abdullah, T.; Tabacaru, G.; Trache, L.; Tribble, Robert E. (American Physical Society, 2007)
      We observed single and double proton emissions in the O-14+He-4 interaction by the thick target inverse kinematic (TTIK) method at initial energy for O-14 at 32.7 MeV. We found that the protons mainly originate from the ...
    • Structure of N-12 using C-11+p resonance scattering 
      Perajarvi, K.; Fu, Changbo; Rogachev, G. V.; Chubarian, G.; Goldberg, V. Z.; Guo, F. Q.; Lee, D.; Moltz, D. M.; Powell, J.; Skorodumov, B. B.; Tabacaru, G.; Tang, X. D.; Tribble, Robert E.; Brown, B. A.; Volya, A.; Cerny, Joseph. (American Physical Society, 2006)
      The level structure of N-12 has been investigated from 2.2 to 11.0 MeV in excitation energy using a C-11+p resonance interaction with thick targets and inverse kinematics. Excitation functions were fitted using an R-matrix ...
