Nucleonica Physical Constants updated to 2018 CODATA recommended values

August 13th, 2019
by Joseph Magill

The values of the physical constants used in Nucleonica are recommended by CODATA and are the latest available. Termed the “2018 CODATA recommended values” they are recognized worldwide for use in science and technology. The values became available on 20 May 2019 and replaced the 2014 CODATA set. They are based on all data available until 31 December 2018.NewPCs-2019Of particular important to the Nucleonica applications, IUPAC is recommending a new definition of the mole based on a specified number of elementary entities:
The mole, symbol mol, is the SI unit of amount of substance. One mole contains exactly 6.022 140 76 × 1023 elementary entities. This number is the fixed numerical value of the Avogadro constant, NA, when expressed in mol−1, and is called the Avogadro number.
