For the first time, magnetically induced (MI) transitions of the D2 line of the 39K atom in an external magnetic field of 10–600G using circularly polarized radiation σ + and σ – have been investigated. According to the selection rules in a zero magnetic field, transitions between sublevels of the ground and excited levels of the hyperfine structure with Fe - Fg = delta F = ± 2 are prohibited, while in the magnetic field there is a giant increase in their probabilities. For MI transitions, Fg = 1-> Fe = 3(delta F = +2) the highest probability is achieved when using σ+ radiation, and for Fg = 2->Fe = 0 the highest probability is achieved when using σ-  radiation. For the atomic transitions spectral separation the process of selective reflection of laser radiation from nanocell, filled with potassium atoms is used. This which allowed us to study the behavior of the MI transitions. The experiment well consistent with the theory.

Van de Hulst (Paper 64, Table 1) has marked optical polarization as a questionable or marginal source of information concerning magnetic field strengths. Rather than arguing about this–I should rate this method asq+-, or quarrelling about the term ‘model-sensitive results’, I wish to stress the historical point that as recently as two years ago there were still some who questioned that optical polarization was definitely due to magnetically-oriented interstellar particles.

Various methods of observing the galactic magnetic field are reviewed, and their results summarized. There is fair agreement about the direction of the magnetic field in the solar neighbourhood:l= 50° to 80°; the strength of the field in the disk is of the order of 10-5gauss.

Observations at various frequencies between 136 and 1400 MHz indicate a considerable amount of structure in the galactic disk. This result appears consistent both with measured polarization percentages and with considerations of the strength of the galactic magnetic field.
