Reexamination of ${}^6\mathrm{Li}+p$ elastic scattering in inverse kinematics

Elastic-scattering measurements have been performed for the ${}^6\mathrm{Li}+p$ system in inverse kinematics at the energies of 16, 20, 25, and 29 MeV. The heavy ejectile was detected by the large acceptance MAGNEX spectrometer at the Laboratori Nazionali del Sud in Catania, Italy. The results are considered in a Jeukenne-Lejeune-Mahaux and a continuum discretized coupled-channel calculation framework.

Figure 1

A reconstructed $E\text{−}\theta$ correlation plot for ${}^6\mathrm{Li}+p$ at a projectile energy of 29 MeV. The two kinematical solutions of the reaction were obtained in three different runs with three sets of magnetic fields. The plot shows the superposition of these runs, designated with different colors. The black solid line represents the theoretical prediction which seems to describe perfectly well the data, giving further support to the accurate spectrum reconstruction.

Figure 2

Present elastic-scattering data for ${}^6\mathrm{Li}+p$ at 16 MeV are compared with JLM and CDCC calculations (see the text). The uncertainty in the data points is between 8% and 10%. This error includes the statistical error, errors due to the target thickness, the beam flux measurement, and the solid angle determination.

Figure 3

The same as in Fig. 2 but for a projectile energy of 20 MeV.

Figure 4

The same as in Fig. 2 but for a projectile energy of 25 MeV.

Figure 5

The same as in Fig. 2 but for a projectile energy of 29 MeV. It should be noted that for this energy, the calculations CDCC1 and CDCC2 gave the same results therefore lines are not distinguished one from the other.
