Isotope separation by laser deflecting an atomic beam is analyzed theoretically. Interacting with a tilted one-dimensional optical molasses, an ytterbium atomic beam is split into multi-beams with different isotopes like 172 Yb, 173 Yb, and 174 Yb. By using the numerical calculation, the dependences of the splitting angle on the molasses laser intensity and detuning are studied, and the optimal parameters for the isotope separation are also investigated. Furthermore, the isotope separation efficiency and purity are estimated. Finally a new scheme for the efficient isotope separation is proposed. These findings will give a guideline for simply obtaining pure isotopes of various elements.Isotope separation by laser deflecting an atomic beam is analyzed theoretically.

Single-atom detection of calcium isotopes by atom-trap trace analysis

We demonstrate a combination of an isotopically purified atom beam and a magneto-optical trap which enables single-atom detection of all stable isotopes of calcium (40, 42, 43, 44, 46, and 48). These isotopes range in abundance from 96.9% $(^{40}\mathrm{Ca})$ to 0.004% $(^{46}\mathrm{Ca})$ . The trap is loaded from an atomic beam which is decelerated in a Zeeman slower and subsequently deflected over an angle of 30\ifmmode^\circ\else\textdegree\fi{} by optical molasses. The isotope selectivity of the Zeeman slower and the deflection stage is investigated experimentally and compared with Monte Carlo simulations.We demonstrate a combination of an isotopically purified atom beam and a magneto-optical trap which enables single-atom detection of all stable isotopes of calcium (40, 42, 43, 44, 46, and 48).
