Description	Journal: Journal of Physics B: Atomic, Molecular and Optical Physics The fine-structure effect associated with electron impact excitation of LS-coupled atomic targets from the$ ^{1}$S ground state to a $N^{3}$L final state is discussed. The relationship between the electron impact coherence parameters (EICP) and the fine-structure effect spin-polarisation function is illustrated for the case of excitation of the N^{3}$D_{J}$ (J=1, 2, 3; N=3, 4,. . . 8) states of helium. It is shown that for L>or=3 (i.e., $N^{3}$F, $N^{3}$G, etc.) excitation processes, the electron spin-polarisation experiments provide different information from that obtained from electron-photon coincidence experiments. If data from spin-polarisation and EICP experiments can be combined, information about the octupole moment of the electron impact induced final atomic state can be obtained.
