I'm working on a paper about the Belousov-Zhabotinsky-reaction (a chemical oscillator).
I included some information about the history of oscillation reaction, in particular about Boris Pavlovich Belousov and Anatol Markovich Zhabotinskii.
Boris Belousov was the first to discover the Belousov-Zhabotinsky-reaction (BZ-reaction), whilst Zhabotinsky later continued Belousovs research.
My problem now is the year that Boris Belousov died. I have a few contradicting sources. The year is 1970 or 1976.
Some sources that say 1970: Wikipedia, Nature, Handbook on the Physics and Chemistry of Rare Earths.
Source that says 1976: Journal of Biosciences. This source does not have references on where the year 1976 came from.
Do you agree that I should use 1970, because that is what most sources say? Or is it more plausible that it is 1976, because that source has a DOI? But on the other hand, the second source did not include references on the year of death..
