The lead isotopes and natural abundances are:
El. Abundance
204Pb 1.4% (1.4x10^17 y half-life)
206Pb 24.1%
207Pd 22.1%
208Pd 52.4%
Note: "pd" above is a typo, and should be "Pb".
Unfortunately, of the above isotopes of lead, only 207Pb has a
nuclear moment, which is useful in increasing tunneling probability.
More interesting from the perspective of magnetic moment is 209Bi,
which has a 100% abundance, and a large nuclear magnetic moment in
comparison to 208Pb. The nuclear catalysis LENR reaction is:
209Bi83 + 2 D* -- 213At85 --> 4He2 + 209Bi83 (125 ns)
