I have been searching for a table of nuclear mass for a long time, but what I got are mostly data of atomic mass. The mass of electrons and the atomic binding energy might bring error to the calculation involving nuclear mass.

You need a chart of the nuclides which you can access on line. There used to be posters of this but i don't know if its still sold. LiveChart has an interactive display and Wikipedia has a chart on their web site but it doesn't have your data included. The chart on Wikipedia is not complete but gives you an idea of how big the Chart of the Nuclides is. There is a very useful chart here that appears to be complete. You can scroll in and out looking for a nucleus. Once you find one you want you can click on the square and it lists a large amount of data for each nucleus. There are literally thousands of nuclides.

  • $\begingroup$ Note that both of those links seems to be displaying data from the ENSDF/NNDC, whose definitions of mass, mass excess, and binding energy seem to lump nuclear and electronic binding energy together. The total electronic binding energy is quite significant for large-$Z$ nuclei. $\endgroup$
