General Comments:

Mass measurements: 2011Ha48, 2007Ha20, 2004Ge18

1969We11: identification of 118Pd isotope in 235U(n,F) reaction followed by chemical separation of products and parent.

Later work by 1989Ko22 (also 1988Pe13) isolated this isotope in 238U(p,F) reaction by ion-guided on-line mass separation.

1993Ja03: 238U(p,F) reaction, on-line mass separation, detailed study of decay of 118Pd to 118Ag.

Theoretical calculations: 27 references (21 for structure and seven for half-lives and decay modes) from the NSR database available at www.nndc.bnl.gov/nsr/ are listed in the ’document’ records in this dataset.

Q-value: S(2n)=11700 7, S(2p)=25897 4 (2021Wa16)

E(level): From least-squares fit to Eγ values, assuming 0.5 keV uncertainty for Eγ, when not given. Note that low reduced χ2 0.041 reflects the fact that most of the levels decay by single γ rays.
