Cross sections for excitation of the 1s{sup 2}2s2p {sup 3}P{sub J}{sup 0} {r_arrow} 1s{sup 2}2s2p {sup 3}P{sub J}{sup 0}, fine-structure transitions in beryllium-like ions by proton, deuteron, triton, and {alpha}-particle impact have been calculated using a close-coupled impact-parameter method. This technique includes the effects of dipole coupling to the nearby triplet 2p{sup 2}, 2s3s, and 2s3d configurations by means of a polarization potential. The authors consider the ions C III, N IV, O V, Ne VII, Mg IX, Al X, Si XI, S XIII, Ar XV, CaXVII, Ti XIX, Cr XXI, Fe XXIII, and Ni XXV. Excitation rate coefficients have also been calculated from the cross sections for a range of temperatures.
