These are the values of the 1932 experiment with NIST 2024 data: Lithium7 amu 7.0160034366 Hydrogen amu 1.00782503223 8.02382846883 Helium amu 4.00260325413 Helium amu 4.00260325413 8.00520650826 Difference (amu) 0.01862196057 Difference (eV) 17.3462464706347E+06 Difference (J) 2.7791750783E-12 Is this the level of precision that you claim to exist with E = mc²? Check this out: HISTORY OF THE RECOMMENDED ATOMIC-WEIGHT VALUES FROM 1882 TO 1997: A COMPARISON OF DIFFERENCES FROM CURRENT VALUES TO THE ESTIMATED UNCERTAINTIES OF EARLIER VALUES https://www.ciaaw.org/hydrogen.htm For Hydrogen, they don't go further than 5 decimals. Not to mention Li7, which seems to pose some problems since ever, even with the best mass spectrometry instrumentation. ---------------------------------------------------------------- QUOTE: Atomic mass units (AMU) are a unit of mass used to measure atomic masses, while atomic weight is the average weight of an element's isotopes: Atomic mass units: A unit of mass used to measure atomic masses. One AMU is equal to 1/12 the mass of a carbon-12 atom in a grounded state. AMU is also known as a Dalton. Atomic weight: The average weight of an element's isotopes, taking into account their relative abundances. Atomic weight is measured in AMU. --------------------------------------------------------------- So, how can NIST publish up to 10 decimal digits, if those who ACTUALLY measure atomic weight and amu of elements uses 5 decimal digits? These guys, from CIAAW, recollect and distribute data. NIST uses it. https://www.ciaaw.org/members.htm CIAAW is part of the International Union of Pure and Applied Chemistry (IUPAC), which publishes revised tables of RECOMMENDED atomic-weight values. Collision, collusion. Which is the difference?
