计算了假设的土星辐射带的几个同步加速器光谱。假设相对论性电子的单能分布存在于与旋转轴对齐的偶极磁场的环面体中。当同步辐射加入到波长小于50 cm的观测所暗示的热成分中时，根据临界波长和辐射电子的数量密度，总发射光谱的上升可以变得逐渐到相当急剧。作为一个例子，磁场强度、电子能量和密度的范围被制成表格，用于估计在最长分米波长观测下的非热成分。目前的观测不足以确定临界波长；但是，对于几种磁场载荷因子的估计，计算了最小表面磁场强度和最小电子数密度。
Several synchrotron spectra are computed for a hypothetical Saturnian radiation belt. A monoenergetic distribution of relativistic electrons is assumed to exist in a toroidal volume in a dipole magnetic field aligned with the rotation axis. When synchrotron emission is added to the thermal component implied by observations at wavelengths shorter than 50 cm, the upturn in the total emission spectrum can become gradual to quite sharp depending on the critical wavelength and the number density of radiating electrons. As an example, the ranges of magnetic field intensity, and electron energy and density are tabulated for an estimate of the nonthermal component at the longest decimetric wavelength observation. The present observations are insufficient to determine the critical wavelength; but, for several estimates of the magnetic field loading factor, the minimum surface magnetic field intensity and minimum electron number density are computed.
