Large-scale R-matrix calculations are carried out for the electron-impact excitation of Ne{sup 3+} and Ne{sup 6+}. For Ne{sup 3+}, a 581-LSJ-level R-matrix intermediate coupling frame transformation calculation is made for excitations up to the n=4 shell. For some transitions, large effective collision strength differences are found with current 23-jKJ-level Breit-Pauli R-matrix and earlier 22-LSJ-level R-matrix jj omega (JAJOM) calculations. For Ne{sup 6+}, a 171-jKJ-level Breit-Pauli R-matrix calculation is made for excitations up to the n=5 shell. For some transitions, large effective collision strength differences are found with current 46-jKJ-level Breit-Pauli R-matrix and earlier 46-LSJ-level R-matrix JAJOM calculations. Together with existing R-matrix calculations for other ion stages, high-quality excitation data are now available for astrophysical and laboratory plasma modeling along the entire Ne isonuclear sequence.
