Atomic Mass and Nuclear Binding Energy for Np-221 (Neptunium)

This document is part of the Supplement containing the complete sets of data of Subvolume B ‘Nuclei with Z = 55 - 100’ of Volume 22 ‘Nuclear Binding Energies and Atomic Masses’ of Landolt-Börnstein - Group I ‘Elementary Particles, Nuclei and Atoms’, and additionally including data for nuclei with Z = 101 - 130. It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Np-221 (Neptunium, atomic number Z = 93, mass number A = 221).
