本文描述测量离子能量的光学共振方法,这种方法利用多普勒效应把离子能量与离子的光学共振激发联系起来,可应用在leV—100MeV能区,在30keV附近,它的测量准确度可望达到5×10-5,用这种方法测量了142Nd+离子能量,获得了较好的结果。An optical resonance method for measuring ion energy has been suggested. The experimental details are described. The method relates the resonant oprical transition of ions and the ion energy through the Doppler effect. The method can be applied in the energy range of leV-100 MeV, and its accuracy is expreted to reach 5×10-5 near energy of 30 keV. We have measured the 142Nd+-ion energy by this method and the result is fairly good.
