【 摘 要 】

Momentum distributions of strontium atoms are characterized by means of bimodal functional dependences, which properties depend on the laser field parameters. It is shown that ultracold fraction of atoms (T ≤ hγ/kB) can reach 60 %. The calculations are based on the quantum treatment of the problem with taking into account the recoil effect in full. The results can be used for ultradeep laser cooling of strontium atoms.
