论文摘要
存在两种方法来查找电子的磁矩。在量子电动力学中使用的第一个中，一个人计算出恒定磁场中的电子能量，这是由于该场与磁矩成正比的额外能量。还可以使用第二种方法来进行以下事实：无穷大的矢量电位的渐近形式与磁矩成正比。如果电子类似点状，则两种方法都将产生相同的结果。在本文中，研究了由电子在氢样离子中产生的磁场，这使人们能够通过第二种方法找到电子磁矩。在这种情况下，在这种情况下，电子磁矩在离子库仑场的不同状态下被证明是不同的，而且，与第一种方法计算的磁矩不同。本文的结果表明，电子不小，并且在外部场的作用下是可变形的。
There exist two methods for finding the magnetic moment of the electron. In the first of them employed in quantum electrodynamics, one calculates the energy of the electron placed in a constant magnetic field, the extra energy due to the field being proportional to the magnetic moment. It is also possible to use the second method proceeding from the fact that the asymptotic form of the vector potential at infinity is proportional to the magnetic moment. If the electron were point-like, both the methods would yield identical results. In the present paper is studied the magnetic field created by the electron in hydrogen-like ions, which enables one to find the electron magnetic moment by the second method. The electron magnetic moment in this case proves to be different in different states of the electron in the Coulomb field of the ions and, moreover, is distinct from the magnetic moment calculated by the first method. The results of the paper show that the electron is not small and is deformable under action of external fields.
