Break-up of 6Li and 7Li on tin and nickel nuclei

Measurements of angular distributions for7Li elastically scattered from58Ni at energies around the Coulomb barrier

“…Comparison of the elastic scattering angular distribution for E lab = 14.22 MeV between data reported in the present work and those by Pfeiffer K O et al [29]. The curves (black solid line and red dashed line) correspond to optical model calculations using the SPP for the real part and a Woods-Saxon shape for the imaginary part for each set of experimental points (the parameters are shown in table 1).…”

“…In this work, we present preliminary angular distributions of 7 Li elastically scattered from 58 Ni for five out of the ten energies measured. Preliminary calculations using the optical model potential (OMP) are also reported as well as a comparison with data reported by Pfeiffer K O et al [29] and by Zerva K et al [30].…”

“…[29], see text for further information. [29] As part of the analysis presented in this work, a comparison of the elastic scattering angular distribution for E lab = 14.22 MeV between data reported by Pfeiffer K O et al [29] and the present work was made, as shown in figure 3.…”

“…[29], see text for further information. [29] As part of the analysis presented in this work, a comparison of the elastic scattering angular distribution for E lab = 14.22 MeV between data reported by Pfeiffer K O et al [29] and the present work was made, as shown in figure 3. From this figure, it is possible to see that the preliminary experimental data reported in this work, for this energy, are in good agreement with respect to the data reported back in 1973 by Pfeiffer K O et al [29].…”

“…In this context, it came to our attention that the information existent on elastic scattering angular distributions covering a wide angular range for 7 Li on medium targets at energies below the Coulomb barrier is very scarce. Most of the measurements reported correspond to energies near but above the Coulomb barrier; 7 Li+ 58 Ni [29], 7 Li+ 59 Co [26], 7 Li+ 64 Ni [21]. In addition, the measurements reported for energies near but below the Coulomb barrier for 7 Li+ 58 Ni are not full angular distributions as reported by Zerva K et al [30], where the elastic backscattering technique is used.…”
