Elastic scattering of protons by He-4 was thouroughly studied in Phys. Rev. C15 (1977) 518. Based on different sets of experimental data the R-matrix parameterization of the cross sections was produced. More recent measurements reported in NIM B136-138 (1998) 77 confirmed the consistency of the parameterization and new experimental results. The analysis reported in NIM B174 (2001) 33 also supported the obtained R-matrix parameterization with some corrections. The parameterization of the last paper is presented here.
