Nuclear Data Sheets for A = 51

The 1997 version of nuclear data sheets update for A = 51 (1997Zh09) has been revised and updated on the basis of the experimental results from various decay and reaction studies since January 1997. Detailed level and decay schemes are presented for the nuclei of the A = 51 mass chain. The data sets of levels, gammas for 51Ti, 51Sc, 51Cr, 51Mn, and 51Fe are expanded. The experimental methods, references, Jπ arguments, and necessary comments are given in the text.
