个人简介
Lajos’s most significant contribution from the Hungarian Mössbauer community’s point of view was reproducing the 57Fe Pound–Rebka experiment as early as November 1960 at KFKI and establishing the first Mössbauer group in the country. Together with his co-workers, Lajos first demonstrated the Mössbauer effect on 159Tb in 1962. Other Mössbauer isotopes used in his group in the sixties included 197Au, 119Sn, and 161Dy. Major topics investigated in his group using Mössbauer spectroscopy initiated mainly by him comprised the glass transition in frozen aqueous solutions and the determination of hyperfine fields from the perturbed angular distribution of Mössbauer-scattered radiation. A new Mössbauer group devoted to biophysics was organized by Lajos in Szeged after 1973 when he moved to the Biological Research Centre. In an experiment proposed by him during this period (performed at KFKI, though) an upper limit was established for the difference of the absorption of right and left circularly polarised γ-quanta in L and D amino acids using elliptically polarised Mössbauer radiation.
Besides many other topics, Lajos focused in biophysics on two main subjects. First, he followed the exciting question of whether the parity violation observed in β-decay can be connected to the difference in the frequency of occurrence of the L and D enantiomers of biomolecules and continued proposing further experiments to answer. Second, he systematically investigated the proton pumping mechanism in bacteriorhodopsin, an ion-transporting membrane protein converting light energy into chemical energy in nature.
