But my point was, it's not a nuclear fusion from what are ordinarily considered nuclear reactant candidates in terrestrial fusion projects.
My understanding is that pair-production collapse only occurs in post-Helium stars. A citation by two of the same investigators of more recent vintage, I believe, says oxygen fusion chain reactants are in play at this point in the star's life:

OK, but MY point was that the "ignition" being referred to in ICF is a chain reaction, and not just "burning" at some low rate of consumption, as in the sun:
The energy released by these reactions will then heat the surrounding fuel, and if the heating is strong enough this could also begin to undergo fusion.The aim of ICF is to produce a condition known as "ignition", where this heating process causes a chain reaction that burns a significant portion of the fuel.
"These reactions" refers to the fusion caused by the laser heating, which plays the role of the fission "trigger" in an H-bomb, as I understand it. This is thermonuclear ignition, like an H-bomb, and like a pair instability supernova, but not like the sun.
