dc.description For pt.I see ibid., vol.18, no.4, p.589 (1985). The transition rates for transitions among the 3s and 3p excited fine-structure levels of neutral neon are calculated and compared with experimental observations. The method of calculation involves accurate non-relativistic calculation of the wavefunctions in LS coupling followed by diagonalisation of the Breit-Pauli Hamiltonian to yield the fine structure. Particularly in the case of the 3p levels, very slight errors in the non-relativistic energies can lead to very significant errors in the relativistic level-mixing coefficients with consequently large errors in the transition rates. A method for correcting energy levels, based on inverting the eigenvalue problem using the eigenvalues (the observed level energies) as known input, allows accurate determination of level-mixing coefficients, and hence transition rates, in a test case involving levels that are strong mixtures of three terms. The paper extends earlier work by demonstrating that the method remains effective for obtaining corrected mixing coefficients in a somewhat more complicated situation involving levels with significant mixtures of four non-relativistic terms as well as in cases where only two terms are mixed. The resulting transition rates compare well with observation and some discussion of the errors implicit in the method indicates that the method is stable and accurate in the context of such transition rate calculations.
