Soviets Experience Difficulties In Development of Laser Isotope Separation Method On two totally unrelated occasions recently, Soviet scientists asked openly for details on US laser isotope separation (LIS) research and indicated that they were having problems.
A.M. Prokhorov has openly referred to the institute's work aimed at uranium LIS using uranium hexafluoriderokhorov asked for US details on relaxation times, indicating that the Soviets are working on the two-step photodissociation process.
a Gleb V.aser specialist from
the Lebedev Physics Institute, brought up the subject of LIS, although he himself is not involved in it. He said that the Krasnaya Pakhra Institute of Spectroscopy is having difficultyiable commercial LIS process, and workers there need information about US efforts. While he would not confirm or deny the existenceoviet uranium LIS program, he said that the Soviets had not been very successful in LIS so far. He added that the amounts separated were small and the processes rudimentary.
Comment: Thisis the firstoviet (Prokhorov) has admitted the existencepecific program to separate uranium isotopes by LIS. Apparently the Soviets have successfully separated small amountsy laboratory techniques similar to those in US experiments at Livermore and Avco laboratories using metallia uranium. The Soviets are clearly havinewith the chemistry of UFg for LIS.
