摘要： Using the path integral method, we calculated all the distribution probability ratios for the spin projection of the electron in a hydrogen atom under the disturbance of a strong periodic magnetic field, and studied the screening effect of the coupling of spin with the periodic magnetic field B(t) on the ratios of the spin distributions. It is found that the screening exists not only in the usual direction along the magnetic field (not affected by initial conditions) but also other directions affected by the initial conditions. For the valence electron in the alkali metals, such as 3/sup>Li, 11Na, 19K, 37Ru, and 55Ce, etc., a similar conclusion can be drawn.

Abstract: Using the path integral method, we calculated all the distribution probability ratios for the spin projection of the electron in a hydrogen atom under the disturbance of a strong periodic magnetic field, and studied the screening effect of the coupling of spin S with the periodic magnetic field B(t) on the ratios of the spin distributions. It is found that the screening exists not only in the usual direction along the magnetic field (not affected by initial conditions) but also other directions affected by the initial conditions. For the valence electron in the alkali metals, such as 3Li, 11Na, 19K, 37Ru, and 55Ce, etc., a similar conclusion can be drawn.
