内容記述 | The object of the experiment was to investigate whether the separations of iron and nickel lines are proportional to the fields applied. For measuring the strength of the fields, the zinc line λ:4680 138 was adopted, as the separation of the line has been accurately determined by many observers. In groups ""g"", ""h"", ""i"" and ""j"", this line was simultaneously photographed on the same plate with iron and nickel lines. The simultaneous photograph, however, limited the number of lines to be studied, consequently I was obliged to photograph this line before and after the photography of iron lines (groups ""e"" and ""f""). Concave grating was used for obtaining spectra of the lines from the second to the fifth order. The sharp triplets show separations of their outer two components proportional to the fields applied; but in the case of most of the diffuse triplets, these separations are not proportional to the fields; in some diffuse lines, Δλ/H is constant in weak fields but becomes larger in the stronger; in other diffuse lines, the deviations from the mean are too large to assume Δλ/H as constant. Arthur King observed these lines with larger grating and took these diffuse triplets for more complicated separated lines. In the course of investigation, the range of spectra photographed was taken as wide as possible at single fields. The results thus obtained are compared with the published data. λ:3345.13 of zinc is also measured in different fields. The separation of this line is linearly proportional to the fields. In conclusion I express my sincere thanks to Professor Nagaoka, at whose suggestion I undertook this investigation and by whose kind guidance I have been able to carry out the experiment. | |||||
