The spin magnetic moment of a single proton in a cryogenic Penning trap was coupled to the particle's axial motion with a superimposed magnetic bottle. Jumps in the oscillation frequency indicate spin flips and were identified using a Bayesian analysis.
在低温彭宁阱中,单个质子的自旋磁矩通过叠加的磁瓶与粒子的轴向运动相耦合。振荡频率的跃变表明自旋翻转,并通过贝叶斯分析进行识别。
