Selection and Focusing of Polar Diatomics in States of Positive Induced Electric Dipole Moment Using a Ten-Pole Field

Abstract

Using a ten-pole electric field (with two-pole symmetry) it has been possible to select and focus the rotational states J, M = 0, 0; 1, ±1; and 2, ±2 for velocity-selected thermal molecular beams of CsF and RbCl. However, because of the nonideality of this focusing field, the enhancement in intensity of the separated states (focusing effect) over the thermal population is only about a factor of 2.
