A polarization technique based on the detection of Zeeman quantum beats in transmission is applied to the determination of multipole relaxation rates in ground or near-ground atomic levels. With an appropriate choice of polarization and geometry, beat signals are obtained whose decay directly yields the relaxation rates of orientation or alignment. The technique has been used to study collisional depolarization in the 4f/sup 6/6s/sup 2/ /sup 7/F/sub 1/ near-ground level of Sm I by rare-gas perturbers. Derived cross sections are compared with previous, widely-differing determinations.
