[en] Evaluated nuclear structure and decay data for all nuclei within the A=207 mass chain are presented. The experimental data are evaluated and best values for level and gamma-ray energies, quantum numbers, lifetimes, gamma-ray intensities, and other nuclear properties are recommended. Inconsistencies and discrepancies that exist in the literature are noted. This work supersedes the earlier evaluation by M.J. Martin (1993Ma73), published in Nuclear Data Sheets70, 315 (1993).

[en] During November 1994 and January 1995, systematic mass measurements in the neutron deficient region of Z element of (56..85) were performed at the Experimental Storage Ring ESR of the GSI. The masses of more than 300 different nuclides were measured directly, about 100 of them had not been measured before. We present the method of evaluating atomic masses from the Schottky spectra, its limitations and accuracy. Some of the measured masses are compared to the results of nuclear mass models. As we have measured masses of several isotopes which belong to α-decay chains with well known decay energies, we determined additionally 62 new masses of isotopes in those chains up to the proton drip line.
