Energy levels of light nuclei A = 13–15

“…See also (1971BE60, 1972BA1R). For reaction (a) see (1971KN05). For reaction (b) see (1969VO10, 1972SC03; E( 19 F) = 40, 60 and 68.8 MeV).…”

Elastic and inelastic scattering of 13C + 18O versus 12C + 18O and 13C + 16O

“…New angular-distribution data for 13 C + 18 O elastic and inelastic scattering at E lab ( 18 O) = 105 MeV were measured for transitions to E x = 0.0-5.26 MeV states of 18 O and E x = 0.0-3.854 MeV states of 13 C. These data and previously published 13 C + 18 O elastic-scattering data at E lab ( 18 O) = 15, 20, 24 MeV [3], 31 MeV [4] and E lab ( 13 C) = 24 MeV were analyzed with the optical model and coupled-reaction-channels methods. The transitions to the excited states were calculated using the rotational and vibration models.…”

“…The 13 C + 18 O elastic scattering data at E lab ( 18 O) = 15, 20, 24 MeV [3], 31 MeV [4] and E lab ( 13 C) = 24 MeV [5] were also included in the OM (first stage) and CRC (final stage) analyses. In the determination of the energy dependent potentials, the real potential parameters were adjusted using corresponding volume integrals as a guide rather than treating them as completely free parameters.…”

“…The use of inverse kinematics in the present experiment makes it possible to measure both forward and backward angle data simultaneously. The present 13 C + 18 O elastic and inelastic scattering data were then combined with previously measured data at the energies E lab ( 18 O) = 15, 20, 24 MeV [3], 31 MeV [4] and E lab ( 13 C) = 24 MeV [5] in optical model (OM) and coupled-reaction-channels (CRC) analyses to obtain parameters of the 13 C + 18 O scattering potential at a range of energies. Special attention was given to understanding the large angle scattering data, where a significant difference with previous 13 C + 16 O data was found.…”

Mécanisme de la réaction 9Be(3He, α)8Be(o) et résonances géantes isoscalaires du 12C

“…On peut donc supposer l'existence d'un niveau au voisinage de 29,4 MeV, mais il n'y a aucune indication quant à sa largeur et à son spin. L'étude de 11 B(p, a)8Be à des énergies incidentes correspondant à la zone d'excitation [25][26][27][28][29][30] MeV dans le 2C [46] montre que cette réaction procède essentiellement par mécanisme direct, mais inhibé par un fort mismatch angulaire, et que, d'autre part, la partie arrière de la distribution angulaire a un comportement résonnant avec l'énergie incidente.…”
