摘要：
We report a measurement of the lifetime of the 1s2s S-1(0) state in two-electron Br33+. This state decays to the 1s2 S-1(0) ground state only by the simultaneous emission of two photons. Ions in the 1s2s S-1(0) level are produced by excitation of energetic bromine ions in a thin carbon foil. The lifetime is determined by measuring the change in the Tate of two-photon coincidences as a function of the foil-detector separation. The lifetime measurement yields 39.32(32) ps in agreement with a theoretical value of 39.63(16) ps.
