Abstract
We study nucleosynthesis in low accretion rate hot advective flows around b lack holes. We find that matter is generally photo-dissociated into protons and neutrons inside the disk. These neutrons stay around black holes for l onger time because they are not coupled to magnetic fields while the proton s accrete into the hole. We find the nature of the resulting neutron disks and estimate the rate at which these disks contaminate the surroundings.
