Inelastic Collisions in Optically Trapped Ultracold Metastable Ytterbium

A. Yamaguchi, S. Uetake, D. Hashimoto +2

We report measurement of inelastic loss in dense and cold metastable ytterbium (Yb[${}^3{P}_2$]). Use of an optical far-off-resonance trap enables us to trap atoms in all magnetic subl…
