“…It can be seen in Table 1 Table 1, Column of five independent parameters that the grazing angular momentum l'g for the phase amplitude 6~ is smaller than the grazing wave angular momentum l'g of the [St[ modulus. The reduced radius r~, half absorption radius corresponding to [St~[=0.50, decreases as the incident energy increases leading to a smaller value of the total reaction cross section a R as expected by some authors [11]. All these values are in agreement with the optical model analysis of M. Buenerd et al [2].…”

An elastic scattering phase shift analysis based on McIntyre parametrization is presented. It has been applied to lzC+ lec system at 360-and 1,016 MeV incident energies as well as to 160 scattering on 12C, 4~ 9~ and 2~ targets at 1,503 MeV. The success of this model allows the interplay between diffraction and refraction to be pinned down: a presence of a nuclear rainbow is clearly evidenced in several cases.PACS: 21.30+y; 25.70Cd.

“…However, in the last years the HEA was modified and applied also to lower energies (see, e.g., Refs. [40,51,63,64,52,65,66,67,35,36]). The prescription to calculate the profile function in this case consists in a replacement of the straight-line trajectory impact parameter (b) by the distance of the closest approach (b c ) in the Coulomb field, or by the respective distance (r cn ) in the presence of nuclear field (ReOP).…”

Abstract. The structure of the exotic 8 B nucleus is studied by means of elastic scattering, as well as its breakup on nuclear targets. We present microscopic calculations of the optical potentials (OPs) and cross sections of elastic scattering of 8 B on 12 C, 58 Ni, and 208 Pb targets at energies 20 < E < 170 MeV. The density distributions of 8 B obtained within the variational Monte Carlo (VMC) model and the three-cluster model (3CM) are used to construct the potentials. The real part of the hybrid OP is calculated using the folding model with the direct and exchange terms included, while the imaginary part is obtained on the base of the high-energy approximation (HEA) and also taken to be equal to the microscopic real part of the OP. In this model the only free parameters are the depths of the real and imaginary parts of OP obtained by fitting the elastic scattering experimental data. It is found a dependence of their values on the model density of 8 B. In addition, cluster model, in which 8

“…As already mentioned in the Introduction, the generalization of the eikonal method made it possible to use it at relatively low energies [41,42,43,44,45,46,47]. In our work, on the base of the eikonal phases we reconstruct the equivalent potential including its imaginary part.…”

“…It is generally believed that the Glauber (eikonal) approximation is reasonable at energies of hundreds MeV and higher. However, beginning from the work [42] the method of HEA has been usually modified by replacing the eikonal straight-line trajectory at an impact parameter b by the parameter b c that corresponds to the distance of the closest approach of the projectile in the Coulomb plus the nuclear potential. For the medium and heavy nuclei the Coulomb distortion dominates and successful applications of the approach were demonstrated, firstly, in [43] and later on in many papers, e.g.…”

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.
