Vj. Foster et al., HEAVY-PARTICLE EXCITATION OF THE FINE-STRUCTURE TRANSITIONS WITHIN THE 2S2P(2) P-4 MULTIPLET IN BORON-LIKE IONS, Monthly Notices of the Royal Astronomical Society, 288(4), 1997, pp. 973-976
Cross-sections are presented for proton-impact excitation of the fine-
structure transitions within the 2s2p(2 4)P multiplet in C II, N III a
nd O IV. These have been calculated using the close-coupled impact par
ameter method modified to include the 2p(3) S-4(o) states by means of
a polarization potential. Excitation rate coefficients have been deriv
ed from the cross-sections for a wide range of temperatures.
