A new measure of Delta alpha/alpha at redshift z=1.84 from very high resolution spectra of Q 1101-264
(2007)
Aims. We probe the evolution of the fine-structure constant a with cosmic time. Methods. Accurate positions of the Fe II lines lambda 1608, lambda 2382, and lambda 2600 are measured in the z(abs) = 1.84 absorption system ...
