In order to generate the precise value for the 21.1cm hyperfine spectral line wavelength in Table A.3, (and hydrogenSpectra2.xls), it was necessary to change the value of d_p from 3.3558912 as reported in [1] and [2], to 3.3548035. This change also reflects the inclusion of P_air, the refractive index of air in the calculation of the 21.1cm line. It subsequently resulted in small variations to the fine structure vacuum emission spectra as reported in [2], which were eliminated via minor changes to the following parameters.

(i) Electron Spin Matter Wave Radius.

(ii) Electron Spin Centrifugal Force Ge Expansion Factor.

This factor has been changed from 7.5% in [2] to 9.5% in this paper. This change is necessary to ensure that the value of G_e in the ground level orbit is below the crossover point A in [2], Fig. 5.1.

All of these changes ensure the following characteristics of the hydrogen spectra predicted by this theory are maintained.

(a) The Lamb Shift in the 2^nd orbit shell, 2s(+) to 2p(-) is 0.353 cm^-1  º 1057.77MHz.

(b) The ground state hyperfine emission line wavelength is 21.106114cm.

(c) The vacuum spectra wavelengths are in perfect agreement with those in [6].

As a consequence there have been some very small changes to the air spectra predicted in [2]. The differences to those in [6] have in a few cases improved and in a few others worsened. These differences are of the order 0.0288Å worst case, {transition 8k(+) Þ 7i(+)}. Full details can be reviewed in the hydrogen spectra spreadsheets available in [2] and this paper, (Appendix A).
