“…For the 14 C-Pb interaction, we use the potential developed in Ref. [25] The Coulomb breakup of 15 C on Pb has been measured at RIKEN at 68 MeV/nucleon [14]. In that experiment, the 14 C core and the valence neutron have been detected in coincidence after dissociation and their relative-energy spectrum has been reconstructed.…”

The Coulomb-breakup method to extract the cross section for neutron radiative capture at astrophysical energies is analyzed in detail. In particular, its sensitivity to the description of the neutron-core continuum is ascertained. We consider the case of 14 C(n, γ) 15 C for which both the radiative capture at low energy and the Coulomb breakup of 15 C into 14 C+n on Pb at 68 MeV/nucleon have been measured with accuracy. We confirm the direct proportionality of the cross section for both reactions to the square of the asymptotic normalization constant of 15 C observed by Summers and Nunes [Phys. Rev. C 78, 011601 (2008)], but we also show that the 14 C-n continuum plays a significant role in the calculations. Fortunately, the method proposed by Summers and Nunes can be improved to absorb that continuum dependence. We show that a more precise radiative-capture cross section can be extracted selecting the breakup data at forward angles and low 14 C-n relative energies.

“…Previously, the microscopic HEA OP was successfully applied in refs. [41,66,67] to describe the 16,17 O+A elastic scattering data at about hundred of MeV/N from [68,46]. Here we would like to give an estimation for the angles of the application of our approach.…”

Abstract. Calculations of microscopic optical potentials (OP's) (their real and imaginary parts) are performed to analyze the 6 He+p elastic scattering data at a few tens of MeV/nucleon (MeV/N). The OP's and the cross sections are calculated using three model densities of 6 He. Effects of the regularization of the NN forces and their dependence on nuclear density are investigated. Also, the role of the spin-orbit terms and of the non-linearity in the calculations of the OP's, as well as effects of their renormalization are studied. The sensitivity of the cross sections to the nuclear densities was tested and one of them that gives a better agreement with the data was chosen.

“…The strong-absorption radius is calculated from an equation which holds the same expression for both of the modified Glauber models I and II. In the modified Glauber model I, the critical angular momentum I, &2 is obtained from (13) However, the angular momentum in the modified Glauber model II is obtained from Eqs. (13) and (9) and takes a somewhat larger value than the one in the modified Glauber model I.…”
