Abstract

We demonstrate the efficient transfer of population from the upper to the lower inversion level within the rotational ground state of para-ND (Formula presented.). A packet of ND (Formula presented.) molecules is velocity controlled and state selected using a Stark decelerator, and subsequently transferred with (Formula presented.) efficiency using the principles of adiabatic rapid passage. Transitions are induced using microwave chirps both under zero-field conditions as well as in the presence of an electric field to probe (Formula presented.) -resolved transition efficiencies. Simulations of the transfer efficiencies based on the von Neumann equation, taking all hyperfine transitions into account, showed excellent agreement with experimental observations.
