Magnetic moment fundamental particles

Abstract. CPT invariance is a fundamental property of quantum field theories in flat space-time. Principal consequences include the predictions that particles and their antiparticles have equal masses and lifetimes, and equal and opposite electric charges and magnetic moments. It also follows that the fine structure, hyperfine structure, and Lamb shifts of matter and antimatter bound systems should be identical. 

For example, the brilliant observation that the electron should be seen not just as a particle charged with electric charge, but also as a carrier of an own magnetic moment , coupled with the Lewis interrogation, i.e., if the octet mle and of the doublet can be somehow reduced to a basic mle , i.e., by forming pairs of electrons - anticipated the fundamental concept of electronic spin and the Exclusion Principle (Pauh principle). 

When we studied the radio-frequency spectrum of D2 we hit another surprise [5]. The separation of the spectral lines in D2 were greater than in H2 even though the nuclear spin-spin interaction and the nuclear spin molecular rotation interaction should be much less. We found a similar anomaly for HD. We finally interpreted this as due the deuterium nucleus having a quadrupole moment (being ellipsoidal in shape) which gave rise to a spin dependent electrical interaction. The existence of the quadrupole moment, in turn, implied the existence of a new elementary particle force called a tensor force. In this way, magnetic resonance made a fundamental contribution to particle physics.
