摘要：

The simplest approximations for a continued-fraction representation of the dynamic relaxation function are used to investigate the spin dynamics of paramagnetic EuO. As the result we can see how the considered approximations predict those wavevectors for which a "spin wave" peak appears in the spectrum. Furthermore, the calculated position of this peak is compared with experiment. The correlation theory within the two-pole approximation is presented in a simple and analytic form.
