Nuclear Data Sheets for A = 140

The 1994 evaluation of A = 140 (1994Pe19) was updated using data available prior to Feb. 1, 2006. The A = 140 mass chain contains 16 nuclei from Te to Ho. Compared to 1994Pe19, the volume of data increased by almost a factor of two, of which about half came from three nuclides: 140La (two (n,γ) E = th datasets), 140Nd (a very rich high-spin dataset), and 140Eu (studied by a combination of techniques covering three new reaction and decay datasets). The main difficulty of this evaluation came from discrepant data for the same three nuclides. For 140La one of the datasets presented many unresolved multiplet levels which were discrepant with the other dataset, and were partially resolved here by the evaluator. For 140Nd the new dataset and the older ones had discrepant γ energies which were recalibrated by the evaluator. The two new high-spin dataset of 140Eu had discrepant Jπ assignments for many levels, which were resolved based on a more recent paper which had accurately established the low Jπ values.
