Nuclear Data Sheets for A = 163

The available data from the various reaction and decay studies leading to nuclides having mass number A=163 have been reviewed. These data are summarized and presented, together with adopted level schemes and properties, for nuclides from Eu (Z=63) through Os (Z=76). 163Eu represents a new addition to these nuclides. Level structures are now known for 163Ta and 163W through high-spin studies and recoil-decay tagging techniques. Several radioactive decays in this mass chain are not known at all or poorly established. No β or γ-ray data are available for 163Re–163W–163Ta–163Hf ε decay chain. Those for 163Hf–163Lu–163Yb ɛ decay chain and 163Eu–163Gd–163Tb β− decay chain are very sketchy. This evaluation is an update and revision of the previous one (2000Si01).
