core-collapse SNII spray everything in (their) sight with neutrons, thereby neutron-enriching elements, far heavier than the iron peak elements.

 

So, could cc SNII create Deuterium, by neutron-enriching hydrogen (the most abundant element in and near them) ?

 

According to A Question and Answer Guide to Astronomy by Pierre-Yves Bely, Carol Christian, Jean-René Roy; the oldest known stars, in Globular Clusters, are enriched in heavy elements, implying that they formed, from intergalactic gas, already enriched, by an earlier generation of primeval stars, of immense mass & luminosity, which reionized the intergalactic medium. If primeval stars processed primordial gas, then perhaps they destroyed primordial Lithium, or created additional Deuterium? How much effect could primeval stars, have had on primordial gas composition ?
