  • In previous analyses of the Oklo (Gabon) natural reactor to test for a possible time variation of the fine-structure constant $\ensuremath{\alpha},$ a Maxwell-Boltzmann low energy neutron spectrum was assumed. We present here an analysis where a more realistic spectrum is employed and show that the most recent isotopic analysis of samples implies a decrease in $\ensuremath{\alpha},$ over the last $2\ifmmode\times\else\texttimes\fi{}{10}^{9}$ years since the reactor was operating, of… CONTINUE READING
