描述了直接测定潘宁阱中存储的单个粒子的自由回旋频率ν(c)的测量方案。该方法基于模式耦合的修饰状态。在这种新颖的测量方案中，单个捕获粒子的两个径向模式同时耦合到轴向振荡模式。
A measurement scheme for the direct determination of the free cyclotron frequency ν(c) of a single particle stored in a Penning trap is described. The method is based on the dressed states of mode coupling. In this novel measurement scheme both radial modes of the single trapped particle are simultaneously coupled to the axial oscillation mode.
