Studies on Laser Isotope Separation in Kyoto University

Laser isotope separation of uranium

A research effort was carried out at the Bhabha Atomic Research Centre (BARC), Mumbai, for developing laser-based techniques for enrichment of natural uranium to reactor-grade (2.5% to 3.0% U), with the potential to be economically scalable to industrial production. Three approaches – two molecular, namely CO2 laser-based approach and UF6-based approach, and one atomic, namely Atomic Vapour Las...

Kyoto University

The recent fuss over one man’s ambition to ‘make Man in his own image’ lends poignancy to Multiplicity, the current exhibition at the Wellcome Trust in London. Timed to coincide with the first anniversary of the arrival of Dolly the cloned sheep, the exhibition presents the reactions of 24 artists to cloning and genetic engineering. Some of the pictures, like Dave Roberts’ mixed media ‘Blueprin...

Kyoto University,

Using Japanese firm-level data, I examine whether multinational enterprises (MNEs) are more productive than non-MNEs in the services sector. I employ the Kolmogorov-Smirnov (KS) test to compare the overall distribution of productivity by multinational status. The results indicate that MNEs tend to be more productive than non-MNEs in the services sector and suggest that the standard firm heterog...

A MODEL STUDY OF LASER ISOTOPE SEPARATION BY PHOTOIONIZATION OR PHOTODISSOCIATION PROCESS

In this study, the selective photoexication of isotopic mixtures by laser light is investigated. Atomic and molecular methods are examined and rate equations are derived for both cases. Two and three step photoionization techniques are considered and rate equations are solved for ion yields. The molecular photodissociation process is also studied and the dependence of the dissociation produ...
