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.
