6. Atomic and nuclear properties of materials 1 6. ATOMIC AND NUCLEAR PROPERTIES OF MATERIALS Table 6.1 Abridged from pdg.lbl.gov/AtomicNuclearProperties by D. E. Groom (2007). See web pages for more detail about entries in this table including chemical formulae, and for several hundred other entries. Quantities in parentheses are for NTP (20 C and 1 atm), and square brackets indicate quantities evaluated at STP. Boiling points are at 1 atm. Refractive indices n are evaluated at the sodium D line blend (589.2 nm); values ± 1 in brackets are for ( n 1) × 10 6 (gases).
