The neutron capture process in stellar nucleosynthesis is considered. The value for the average number of neutrons captured by the seed nuclei exposed to the maximum integrated flux obtained from previous work is considered reasonable on the basis of possible sources of neutron and iron-group abundances in stars. It implies that light nuclei on which ({alpha}, n) occur are at most 100 times as abundant as the iron-group nuclei. It is noted that this value is adequate to produce the observed Pb abundance without appreciable cycling among the Pb isotopes having occurred. The neutron exposure distribution is also obtained from these calculations. (J.F.P.)
