Abstract
The results of experimental studies on creating a source of ultracold atoms 87Rb for an absolute quantum gravimeter based on atomic interference are presented. The studies resulted in sub-Doppler cooling of atoms 87Rb in a magneto-optical trap and in obtaining a cloud ~107 -108 of atoms with a temperature of 6 мкК. Using microwave radiation and optical pumping, the preparation of ultracold atoms in the initial state |F = 1, mF = 0〉is carried out and experiments are performed to observe Ramsey resonances at the transition |F = 1, mF = 0〉 → |F = 2, mF = 0〉during the interaction of the atomic cloud with unidirectional Raman radiation pulses.
