Abstract
This brief report is a follow-up to the recent proposal to use La - as another candidate, in addition to Os-, in laser cooling of anions, which can then be used to cool antiprotons sympathetically. Using the relativistic configuration interaction formalism, we calculate the photodetachment cross sections of the upper laser cooling state La- 5d6s26p 3D1 and Os- 5d66s26p 6D9/2. Our results show that La - has a very similar two-photon detachment loss as Os-, retaining it as another promising candidate for cooling antiprotons sympathetically. © 2010 The American Physical Society.
