A probable two-photon effect is described as a result of focusing an intense pulsed laser beam onto chromosomes of living cells. The effect was suggested after the derivation of a two-photon action spectrum and the demonstration of a lack of reciprocity. 相似文献

Single phase Ti-Fe alloys with up to 50 at. pct Fe were prepared by splat cooling. Alloys with less than about 35 at. pct
Fe consisted of β-titanium solid solution, designated Ti(Fe); alloys with more than 35 at. pct Fe consisted of a partially
disordered, off-stoichiometric TiFe solid solution. The degree of order of this phase was determined. A continuous phase transition
between the ordered and the disordered metastable phase is possible. The ordered metastable phase fulfills known valence electron
concentration criteria for the occurrence of the CsCl structure type.
