We have measured the spin-forbidden decay rate from (3s3d)D-1(2)->(3s3p)P-3(2,1) in Mg-24 atoms trapped in a magneto-optical trap.

Abstract
We have measured the spin-forbidden decay rate from (3s3d)D-1(2)->(3s3p)P-3(2,1) in Mg-24 atoms trapped in a magneto-optical trap. The total decay rate, summing up both exit channels (3s3p)P-3(1) and (3s3p)P-3(2), yields 196 +/- 10 s(-1) in excellent agreement with resent relativistic many-body calculations of Porsev {[}Phys. Rev. A 64, 012508 (2001)]. The characterization of this decay channel is important as it may limit the performance of quantum optics experiments carried out with this ladder system as well as two-photon cooling experiments currently explored in several groups.File in questo prodotto:
