Some technical aspects of the laser isotope separation method

The basic idea underlying laser separation work is explained and the ways in which the general principle is realised, is described for the following methods; photoionization of atoms; photodissociation of molecules; photochemistry; and deflection of atomic beams. A summary is given of experiments which have successfully been demonstrated using these schemes. The requirements and basic arguments which would dictate the main parameters for a plant for large scale production of enriched uranium based on the laser system for photoionization are discussed. Reference is also made to the problems involved in evaporating uranium and in ion collection. (U.K.)
