摘要:
The yields of stable isotopes of Bi, Pb, Tl and Hg as well as yields of205Pb are calculated with a parameterized model for “minir‐processing” in the Ne, O, C‐rich zones of explosive burning in massive stars. The Pb isotopic compositions stand out by their comparatively low207Pb yields and by the fact that thisr‐process variant yields204Pb quite abundantly. The average205Pb/204Pb yield ratio of 6.1 is the same order of magnitude as yield ratios deduced fors‐processing. The Hg from this minir‐process looks like normal solar‐system mercury, but with196Hg missing and the lights‐isotopes A = 198, 199, 200 and 201 depleted (especially t
