LLE Review, Volume 105 26 Introduction In inertial fusion experiments, it is energetically advantageous to form the fuel into a solid shell before compression.1 Current cryogenic target experiments on OMEGA are being performed with pure deuterium (D2) as the fuel. 2 Future cryogenic target experiments will be performed with an equimolar solid mixture of deuterium and tritium (D-T). An equilibri...
متن کاملIsotopic fractionation of tritium in biological systems.
Isotopic fractionation of tritium is a highly relevant issue in radiation protection and requires certain radioecological considerations. Sound evaluation of this factor is indeed necessary to determine whether environmental compartments are enriched/depleted in tritium or if tritium is, on the contrary, isotopically well-distributed in a given system. The ubiquity of tritium and the standard a...
متن کاملExtraordinary isotopic fractionation in ozone photolysis
[1] Analysis of experimental ozone absorption spectra reveals that ultraviolet photolysis within the structured Huggins band yields extraordinary wavelength-dependent isotopic fractionation, oscillating between complete enrichment and complete depletion for changes of less than 2 nm in the excitation wavelength. Visible photolysis yields wavelength-dependent fractionation that varies from 300% ...
متن کاملPhoto-induced isotopic fractionation of stratospheric N2O
Context Abstract: N2O has been identi®ed in the Kyoto Protocol as one of the six greenhouse gases for which anthropogenic emissions should be regulated, however, regulation procedures may not be implemented until a wellde®ned N2O budget has been established. The measurement of N2O isotopic fractionation provides a potential means for constraining the global budget since biological and anthropog...
متن کاملAssessing the short-term stability of spatial patterns of macrobenthos in a dynamic estuarine system
Recent studies of macrofauna on sandflats have emphasized postsettlement dispersal, particularly associated with sediment bedload transport. This study investigated the short-term (3 weeks) stability in spatial patterns of eight common, potentially mobile, near-surface macrofaunal species inhabiting a 4,000-m2 area of intertidal sandflat. Over this period, wind conditions reworked the sediment ...
