摘要：

It is shown that the tunnelling splitting of the energy levels of the easy-axis spin system in a small transverse magnetic field can be calculated perturbationally for arbitrary S. The results are exact, in contrast to those obtained previously in the same limit by indirect and rather difficult methods.
