We present a new assessment of cross section data for excitation of He(l 1S) by proton impact at energies larger than 10keV (in a few cases 6keV). Data for excitation to n1L states of He (n 4, L = S, P and D) are given in tables. The data at high energy (­1000keV) are linked to the first Born approximation and at low energies in some cases to the close coupling AO results of Fritsch, who also made a critical evaluation of the cross sections for excitation of He by protons.
