Abstract：
A simple approach of the Coulomb correction to the p-⁴He low-energy scattering phase shifts is proposed, in which the channel radius of each partial wave is taken as an adjustable parameter. By using the Coulomb correction the n-⁴He scattering observable predicted from p-⁴He scattering phase shifts are in excellent agreement with the experiment. Our calculations show that the neutron polarization depends sensitively on the channel radii of P waves and the obtained channel radii are adequate to all different sets of phase shifts.
