In this Letter, we demonstrate a new scheme for Raman transitions which realize a symmetric momentum-space splitting of 4 Planck's constant k, deflecting the atomic wave packets into the same internal state. Combining the advantages of Raman and Bragg diffraction, we achieve a three pulse state labeled an interferometer, intrinsically insensitive to the main systematics and applicable to all kinds of atomic sources. This splitting scheme can be extended to 4N Planck's constant k momentum… CONTINUE READING
