摘要：

The radiative-decay rates of the 2s(2)2p(P-2degrees)-2s2p2(4P) intersystem transitions of C+ ions have been measured by recording the time dependence of the approximately 233-nm emission. A cylindrical radio-frequency ion trap was used to store electron-impact-produced C+ ions. The time-dependent signals were analyzed by multiexponential least-squares fits to the data. The measured radiative-decay rates to the ground term are 146.4(+8.3,-9.2) s-1 for P-4(1/2), 11.6(+0.8,-1.7) s-1 for P-4(3/2), and 51.2(+2.6,-3.5) s-1 for P-4(5/2). Comparison of the measured values with theoretical values is presented.
