摘要：

A Bose-Einstein condensate is used as an atomic source for a high precision sensor. A 5 x 10(6) atom F = 1 spinor condensate of Rb-87 is released into free fall for up to 750 ms and probed with a T = 130 ms Mach-Zehnder atom interferometer based on Bragg transitions. The Bragg interferometer simultaneously addresses the three magnetic states vertical bar m(f) = 1, 0, -1 >, facilitating a simultaneous measurement of the acceleration due to gravity with a 1000 run precision of Delta g/g = 1.45 x 10(-9) and the magnetic field gradient to a precision of 120 pT= m.
