Depolarization Effects in Pulsed Photoionization of State-Selected Lithium.

摘要

Depolarization effects in pulsed photoionizaton of state-selected lithium atoms have been observed. Experimental evidence and theoretical analysis demonstrate that these effects are produced by resonant excitation of the 2(2)P state. Based upon the analysis, it is argued that resonant excitation of the 2(2)P state with circularly polarized cw laser light followed by broad-band pulsed ionizing radiation can be used to produce an intense highly polarized electron beam with longitudinal polarization.
