Hi there, Salient features:- Cern list of 900 experimental particle results in MeV, double precision and mathematical (Fortran 77) The list alone is not available anywhere-else, as a single list. Not definitive. 42 year scientific project, by ex-Mensa member. (They stopped concessionary subscriptions) 10 year ago table basis was electron value of 227879226. (update IX gives 3224486665) Given the same preview of Periodic table of elements, you would have been champing at the bit, instead of snorting. You are not really into science fiction are you?
