This paper defines a new phase operator for the light field by decomposing the two quadrature phases of the field. The expacted value and fluctuation in the nonclassical states of the light field (number state, coherent state, squeezed state, etc.) are discussed and shown to reduce to the expected classical values in the classical limit. The characteristics of the phase in the squeezed state are revealed in this paper.

Absolute measurements of emission cross sections have been performed for the lines from Arll excited states in Ar~(2+)+Li and Ar~(2+)+Na collision. The energy of incedent ions ranged from 40 keV to 300 keV. The dependence of the emission cross sections on the energy defect AE is discussed. We find that the processes with intermediate △E( > 0) have larger cross sections. We also find that the excited states correlated to the observed lines belong to the high J quantum numbers in an electron configuration.
