    • 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 ...
    • 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-10->Be-9+p 
      Mukhamedzhanov, AM; Clark, HL; Gagliardi, Carl A.; Lui, YW; Trache, L.; Tribble, Robert E.; Xu, HM; Zhou, XG; Burjan, V.; Cejpek, J.; Kroha, V.; Carstoiu, F. (American Physical Society, 1997)
      The differential cross sections for the reactions Be-9(B-10, B-10)Be-9 and Be-9(B-10,Be-9)B-10 have been measured at an incident energy of 100 MeV. The elastic scattering data have been used to determine the optical model ...
    • 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 ...
    • Electron-Transfer from H-2 and Ar to Stored Multiply Charged Argon Ions Produced by Synchrotron Radiation 
      Kravis, S. D.; Church, David A.; Johnson, B. M.; Meron, M.; Jones, K. W.; Levin, J. C.; Sellin, I. A.; Azuma, Y.; Berrahmansour, N.; Berry, H. G.; Druetta, M. (American Physical Society, 1992)
      The rate coefficients for electron transfer from Ar and H-2 to Ar(q+) ions (3 less-than-or-equal-to q less-than-or-equal-to 6) have been measured using an ion-storage technique in a Penning ion trap. The ions were produced ...
    • 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 ...
