We experimentally investigate the formation of subradiant atomic momentumstates in Bose-Einstein condensates inside a recoil resolving optical ringresonator according to the theoretical proposal of Cola, Bigerni, and Piovella.The atoms are pumped from the side with laser light that contains two frequencycomponents. They resonantly drive cavity assisted Raman transitions betweenthree discreet atomic momentum states. Within a few hundred microseconds, thesystem evolves into a stationary subradiant state. In this state, thecondensate develops two density gratings suitable to diffract the two frequencycomponents of the pump field into the resonator. Both components destructivelyinterfere such that scattering is efficiently suppressed. A series ofsubradiant states for various amplitude ratios of the two pump componentsbetween 0 and 2.1 have been observed. The results are well explained with athree state quantum model in mean field approximation.
