Pauli writes about the g-values of neutral and ionized atoms.
Sans titrePauli sends Bohr a manuscript of an unpublished work. He writes about his new interest in quantum theory and his idea to explain the anomalous Zeeman-effect through relativistic considerations. His hypothesis is that the doublet-structure of alkali spectra is alone a property of the valency-electron. He talks about the necessity for a correct formulation of the correspondence principle for atoms with more than one electron and about the necessity for a modification of the classical kinematic concept of motion.
Sans titreHeisenberg writes about Pauli's latest work and congratulates Pauli for all the "lies" contained in it.
Sans titrePauli expresses his doubts about the validity of his exclusion-principle in more complicated cases. He wants to discuss it in Tübingen on Jan. 9 1925.
Sans titrePauli thanks Bohr for the days he spent in Copenhagen.
Sans titreHeisenberg corrects a mistake he made in an earlier letter to Pauli, where he wrote "Einkristall" but meant 'Kristallgitter". He claims that calculation of energy levels in the new quantum mechanics is completely fixed once the multiplication rule for Fourier series is accepted. He is convinced that the new quantum mechanics is correct.
Sans titreHeisenberg writes about recent developments in the formalism of quantum mechanics, perturbation theory and some results for systems with axial symmetry.
Sans titreHeisenberg writes about the problem of continuous spectra from the point of view of quantum mechanics. The effect of time dependent external forces on the atom, and Jordan's calculations of the statistical behaviour of proper vibration of a membrane according to the new theory.
Sans titreBohr has gone through Pauli's "beautiful calculation" on the hydrogen spectrum published in: Zs. Phys. : 36 (1926), pp.336 written with Kramers and Kronig. He will arrange to see Pauli on his return from Leiden.
Sans titreHeisenberg writes about the compatibility of Goudsmit's hypothesis with the formalism of Heisenberg.
