Experimental lifetimes of some laser levels ofCl+

Abstract
We have used the ion-beam method with a gas-jet target to measure the radiative lifetimes of three laser levels (4pP3, 4pD3, 4pF1) and two other levels of Cl+. The levels and lifetimes in nanoseconds are: 4pP3, 11.6±0.6; 4pD33, 8.7±0.9; 4pF31, 12.7±0.6; 4pP23, 5.0±0.6; and 4pP23, 6.7±1.3.
