Calculation of lower bounds to the ground state energy of the C⁺⁺ ion utilizing the technique of reduced density matrices subject to continuously variable N-representability constraints, 1974

Abstract

A recently developed theory enabling the construction of density matrices which are expressible in terms of a given spin geminal set and which are a nearly N-representable as possible is discussed.

Calculation of lower bounds to the ground state energy of the C⁺⁺ ion is performed utilizing reduced density matrices subject to the continuously variable N-representability constraint determined by the above mentioned theory.

Population inversion in a pulsed CO₂-N₂-He discharge, 1971

 Item — Multiple Containers
Identifier: b2088646
Abstract Measurements of the gain in an amplifier discharge tube containing a fixed composition, 1:1.5:5.6, Co₂-N₂-He gas were made under both ac [sic] excited and pulsed discharge conditions. While the ac gain results indicated a possible increase in gain with increasing current densities, the pulsed discharge experiments failed to bear out this extrapolation. Instead, the gain reaches a limit that is apparently...
