    • Astrophysical S factor for Be-9(p,gamma)B-10 
      Sattarov, A.; Mukhamedzhanov, AM; Azhari, A.; Gagliardi, Carl A.; Trache, L.; Tribble, Robert E. (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 ...
    • Astrophysical S factor for C-13(p,gamma)N-14 and asymptotic normalization coefficients 
      Mukhamedzhanov, AM; Azhari, A.; Burjan, V.; Gagliardi, Carl A.; Kroha, V.; Sattarov, A.; Tang, X.; Trache, L.; Tribble, Robert E. (American Physical Society, 2002)
      We reanalyze the C-13(p,gamma)N-14 radiative capture reaction within the R-matrix approach. The low-energy astrophysical S factor has important contributions from both resonant and onresonant captures. The normalization ...
    • Asymptotic normalization coefficients and the Be-7(p, gamma)B-8 astrophysical S factor 
      Azhari, A.; Burjan, V.; Carstoiu, F.; Gagliardi, Carl A.; Kroha, V.; Mukhamedzhanov, AM; Nunes, FM; Tang, X.; Trache, L.; Tribble, Robert E. (American Physical Society, 2001)
      We consider the results of two proton transfer reactions, B-10(Be-7, B-8)Be-9 and N-14(Be-7, B-8)C-13, to obtain a weighted average of the measured asymptotic normalization coefficients for the virtual transition 7Be +pB-8. ...
    • Asymptotic normalization coefficients for B-8 -> Be-7+p from a study of Li-8 -> Li-7+n 
      Trache, L.; Azhari, A.; Carstoiu, F.; Clark, HL; Gagliardi, Carl A.; Lui, YW; Mukhamedzhanov, AM; Tang, X.; Timofeyuk, N.; Tribble, Robert E. (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. ...
    • Asymptotic normalization coefficients for C-13+p -> N-14 
      Trache, L.; Azhari, A.; Clark, HL; Gagliardi, Carl A.; Lui, YW; Mukhamedzhanov, AM; Tribble, Robert E.; Carstoiu, F. (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 ...
    • Beta decay of Ga-62 
      Hyman, BC; Iacob, VE; Azhari, A.; Gagliardi, Carl A.; Hardy, John C.; Mayes, VE; Neilson, RG; Sanchez-Vega, M.; Tang, X.; Trache, L.; Tribble, Robert E. (American Physical Society, 2003)
      We report a study of the beta decay of Ga-62, whose dominant branch is a superallowed 0(+)-->0(+) transition to the ground state of Zn-62. We find the total half-life to be 115.84+/-0.25 ms. This is the first time that the ...
    • Determination of the astrophysical S factor for C-11(p,gamma)N-12 from the N-12 -> C-11+p asymptotic normalization coefficient 
      Tang, XD; Azhari, A.; Gagliardi, Carl A.; Mukhamedzhanov, AM; Pirlepesov, F.; Trache, L.; Tribble, Robert E.; Burjan, V.; Kroha, V.; Carstoiu, F. (American Physical Society, 2003)
      The evolution of very low-metallicity, massive stars depends critically on the amount of CNO nuclei that they produce. Alternative paths from the slow 3alpha process to produce CNO seed nuclei could change their fate. The ...
    • Determination of the direct capture contribution for N-13(p,gamma)O-14 from the O-14 -> N-13+p asymptotic normalization coefficient 
      Tang, XD; Azhari, A.; Fu, CB; Gagliardi, Carl A.; Mukhamedzhanov, AM; Pirlepesov, F.; Trache, L.; Tribble, Robert E.; Burjan, V.; Kroha, V.; Carstoiu, F.; Irgaziev, BF. (American Physical Society, 2004)
      N-13(p, gamma)O-14 is one of the key reactions which trigger the onset of the hot CNO cycle. This transition occurs when the proton capture rate on 13N is faster, due to increasing stellar temperature (greater than or equal ...
    • The N-14(Be-7,B-8)C-13 reaction and the Be-7(p,gamma)B-8 S factor 
      Azhari, A.; Burjan, V.; Carstoiu, F.; Gagliardi, Carl A.; Kroha, V.; Mukhamedzhanov, AM; Tang, X.; Trache, L.; Tribble, Robert E. (American Physical Society, 1999)
      The N-14(Be-7,B-8)C-13 reaction was studied using an 85 MeV Be-7 radioactive beam. The asymptotic normalization coefficients for the virtual transitions Be-7+pB-8 were determined from the measured cross section. These ...
    • Optical model potentials involving loosely bound p-shell nuclei around 10 MeV/nucleon 
      Trache, L.; Azhari, A.; Clark, HL; Gagliardi, Carl A.; Lui, YW; Mukhamedzhanov, AM; Tribble, Robert E.; Carstoiu, F. (American Physical Society, 2000)
      We present the results of a search for optical model potentials for use in the description of elastic scattering and transfer reactions involving stable and radioactive p-shell nuclei. This was done in connection with our ...
    • Scattering of Be-7 and B-8 and the astrophysical S-17 factor 
      Tabacaru, G.; Azhari, A.; Brinkley, J.; Burjan, V.; Carstoiu, F.; Fu, C.; Gagliardi, Carl A.; Kroha, V.; Mukhamedzhanov, AM; Tang, X.; Trache, L.; Tribble, Robert E.; Zhou, S. (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 ...

      Moretto, S.; Fabris, D.; Lunardon, M.; Pesente, S.; Rizzi, V.; Viesti, G.; Barbui, M.; Cinausero, M.; Fioretto, E.; Prete, G.; Brondi, A.; Vardaci, E.; Lucarelli, F.; Azhari, A.; Tang, XD; Hagel, K.; Ma, Y.; Makeev, A.; Murray, M.; Natowitz, J. B.; Qin, L.; Smith, P.; Trache, L.; Tribble, Robert E.; Wada, R.; Wang, J. (American Physical Society, 2004)
      Fusion-evaporation reactions induced by 110 MeV B-11 and radioactive C-11 on Rb-87 targets have been studied by measuring evaporation residue-light particle coincidences. The proton to alpha particle ratio in each reaction ...
    • Tests of transfer reaction determinations of astrophysical S factors 
      Gagliardi, Carl A.; Tribble, Robert E.; Azhari, A.; Clark, HL; Lui, YW; Mukhamedzhanov, AM; Sattarov, A.; Trache, L.; Burjan, V.; Cejpek, J.; Kroha, V.; Piskor, S.; Vincour, J. (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 ...
