We assume an environment of neutrons and α-particles of given density and temperature where nuclear syntheses into 6He, 9Be and 12C are possible. We investigate the resulting relative abundance as a function of density and temperature. When the relative abundance of α-particles Yα is between 0.4 and 0.9, or larger than 0.9, the largest production is 9Be or 12C, respectively. When Yα < 0.4 6He is mostly frequently produced for temperatures above about 2 GK whereas the 9Be production dominates at smaller temperatures.
