This book presents several precision measurements performed on atomic cesium and related to ongoing efforts toward a new measurement of the Weinberg mixing angle at low momentum transfer. The ultimate goal of this research program is an improved measurement of the extremely weak electric-dipole transition moment of the 6 7 transition of cesium, which is strictly electric-dipole forbidden without the weak force. Due to state mixing by the weak interaction, however, the optical transition is allowed, albeit very weakly, 10. The magnitude of yields the weak mixing angle and improving the precision of provides a direct test of the standard model of particle physics. The three specific measurements described in this thesis are: hyperfine coupling constants of several states; the static Stark polarizability of the 7state; and the ratio of the scalar to vector transition polarizabilities for the 67transition. In addition, it describes a new optical phase locking technique developed by the author to allow interference measurements on any of the hyperfine components of the 67transition. This technique is instrumental in a future measurement of .
