类氢氦离子(~4He^+)的兰姆移动测量

Measurement of the Lamb shift in the Hydrogenlike Ions ~4He^+

介绍应用分离振荡技术测量类氢氦离子(~4He^+)的兰姆移动,由于氦原子的核体积精度比氢原子的核体积精度高,从而提高了兰姆移动的测量精度,使理论值和实验值符合得更好。

The paper introduces the use of the separated oscillatory field technique in the measarement of the lambshift of the hydrogenlike ions ~4He^+. Since the charge radius of the ~4He^+ nucleas is more pricise in the order ofmagnitude than the charge radius of the proton, by making the Mmeasurement of the Lamb shift more pre-cise, the value for the Lamb shift is in better agreement with the experimantal values and theoretical values.
