Abstract:

6Li 32D 3/2, 5/2 states were studied using a diode laser to first excite the 2P 3/2 state and a dye laser to populate the 32D 3/2, 5/2 states. The dye laser was modulated by an electro-optic modulator and intersected an atomic beam that passed through a field free region and subsequently through a uniform electric field. A value of 1084.24±0.20 MHz was found for the 32D fine structure splitting. The scalar and tensor polarizabilities were determined to be α (3D 3/2 ) = - 3.753±0.015, α 2 (3D 3/2 ) = 2.893±0.017, α (3D 5/2 ) = - 3.772±0.008 and α 2 (3D 5/2 ) = 4.058±0.013 MHz/(kV/cm)2.
