摘要：
We present the first measurement of an atomic radiative lifetime in Fr. We use a time-correlated single photon counting technique with a cold sample of Fr-210 atoms in a magneto-optic trap. The results are a precision experimental test of the atomic many-body perturbation theory applied to the heaviest alkali. The lifetime for the 7p(2)P(3/2) level of 21.02(16) ns gives a value for the reduced transition matrix element between the levels 7s(2)S(1/2) --> 7p(2)P(3/2) of 5.898(22)a(infinity) atomic units.
