Conclusion 454 References 454 Abstract.A n historical and methodological analysis is given of the scientific heritage of the r e m a r k a b l e Swiss theoretical physicist Walter Ritz ( 1 8 7 8 -1 9 0 9 ) on the basis of a study of his complete w o r k s edited in 1911. T h e general characteristics of R i t z ' s w o r k s -including the p a p e r s on spectroscopy, the variational m e t h o d and electrodynamics -are discussed, and his fundamental research in the theory of atomic spectra is considered in detail. T h e elastic and the magnetic atomic models, p r o p o s e d by Ritz to explain the spectral laws and based on a classical a p p r o a c h , are discussed. It is shown that the generalised Balmer and R y d b e r g formulas and the combination principle, which later b e c a m e a basis for the formulation of B o h r ' s frequency condition, were obtained by R i t z as a result of m a t h e m a t i c a l deductions from his models and were not of a semi-empirical character as is usually believed. General characteristics of Ritz's worksT h e n a m e of Walter Ritz, a Swiss scientist of the beginning of the 20th century, needs no special r e c o m m e n d a t i o n s for physicists. In spectroscopy, the n a m e of R i t z is connected primarily with the combination principle which played an i m p o r t a n t role in the construction by Niels Bohr in 1913 of the initial q u a n t u m theory of the a t o m and its spectrum.

“…For the first time, the 3d-4f transition was observed almost a century ago by Paschen, citing the wavelength of 18697.0 Å 2 [13]. A later measurement of this transition by Johansson [14] yielded a different value for the wavelength, 18703.1 Å, which is quoted in two data tables [6,11].…”

An accurate knowledge of the Li i 4d-4f energy separation is essential for the determination of electric fields, as is pursued using several modern diagnostic techniques. However, there is a rather large spread in the values of this quantity in the available data sources. We have measured the Li i 4d-4f energy separation using a technique that combines laser-induced-fluorescence with the utilization of collisional excitations. The plasma used for these measurements is laser-produced, which allows for selection of an electron-density range for which line shifts due to the plasma microfields are sufficiently small. An observation of the forbidden 2p-4f line provides the information on the microfields that allows for accounting for the Stark-shifts and evaluating the 4d-4f energy separation in the field-free limit. A comparison of the measured value with a few previous measurements allows for resolving the uncertainties in this quantity.
