研究了在静磁场作用下形成的正电子离子的超精细光谱。概括迄今为止在文献中发展的情况，不假设磁场与入射极化正电子的动量平行，而电子极化的可能性也包括在分析中。该结果可用于高灵敏度正电子偏振仪的电流衰减实验。注释：17页（LateX文件；不需要额外的宏）
Hyperfine spectroscopy of positronium formed in the presence of a static magnetic field is considered. Generalising the situation hitherto developed in the literature, the magnetic field is not assumed to be parallel to the momentum of incoming polarised positrons, while the possibility of electron polarisation is also included in the analysis. The results are of application to high sensitivity positron polarimeters used in current $\beta$ decay experiments. Comment: 17 pages (LateX file; no extra macros needed)
