Spin relaxation in alkali-metal..


We discuss the relaxation of a spin-polarized alkali-metal vapor due to the electric-quadrupole interaction in 1 dimers, and present a model that accurately describes the measured relaxation rates under a wide variety of conditions. We use the model along with experimental results to deduce the quadrupole interaction strength, atom-dimer chemical-exchange reaction rate, and the rate of reorientation of singlet dimers due to collisions with the buffer gas =)

My day has been fun. How about yours?
