Plot of R-Process Abundances
The magenta line shows a typical r-process path, and the small magenta squares are the nuclei produced when the nuclides along the path decay back to stability after the supernova neutron flux ends.

Nuclear Ground-State Masses and Deformations, by P. Möller, J. R. Nix, W. D. Myers, and W. J. Swiatecki Atomic Data Nucl. Data Tables 59 (1995), 185-381. The other calculated nuclear properties are from Nuclear Properties for Astrophysical and Radioactive-Ion-Beam Applications, by P. Möller, J. R. Nix, and K.-L. Kratz, Atomic Data Nucl. Data Tables 66 (1997), 131-343. The most recent experimental mass evaluation is Wapstra, Audi, and Thibault (A. H. Wapstra, G. Audi, and C. Thibault, Nucl. Phys. A729 (2003), 129). Another repository of this evaluation and related data can be found here . We use here recent data from the interrim evaulation: G. Audi and W. Meng, Private Communication, April 2011 An exhaustive list of nuclear-mass data bases and other mass-related resources is found here . |
