Fragmentation Barriers of Toroidal and Bubble Nuclei
(American Physical Society, 1994)
With an improved Boltzmann-Uehling-Uhlenbeck model, the deformation energy surfaces in reactions leading to the formation of toroidal and bubble nuclei are examined for central Mo-92+Mo-92 collisions. We found that the ...
Asymptotic normalization coefficients for B-10->Be-9+p
(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 ...
The N-14(Be-7,B-8)C-13 reaction and the Be-7(p,gamma)B-8 S factor
(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 ...
Deuteron Elastic-Scattering at 110 and 120 Mev
(American Physical Society, 1993)
Deuteron elastic scattering cross sections have been measured at 110 and 120 MeV on C, Ni-58, and Pb-208. Optical model potentials have been extracted and compared to deuteron global optical model potentials.
''Bare'' single-particle energies in Ni-56
(American Physical Society, 1996)
The structure of the low-lying levels in the mirror nuclei Ni-57 and Cu-57 is described within the extended unified model. The problem of single-particle energies in Ni-56 is treated in detail. ''Bare'' single-particle ...
Astrophysical S factor for Be-9(p,gamma)B-10
(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 for C-13+p -> N-14
(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 ...
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 ...
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 ...
