Taking into Account the Centre-of-Mass Correlations in the Cross Sections for Elastic Scattering of Intermediate Energy Protons on the Exotic Nuclei 6He and 8He
Abstract
We calculate the differential cross sections for proton elastic scattering on the exotic halo nuclei 6He and 8He at energies around 0.7 GeV at the momentum transfers squared up to 0.30 (GeV/c)2 and investigate the influence of the nucleon centre-of-mass correlations on the calculated cross sections. In particular, we show that the approximate account of the centre-of-mass correlations used previously considerably overestimates the cross sections at high values of the momentum transfer.
