@TheWerewolf the main berillyium isotope produced in stars is Be10 as an intermediate step towards C. The reactions you list are theoretically possible, but hardly ever happen in stars (low reaction rates) - thb, I'd need to look up whether they would produce energy at all. Where do you have them from?
@vicgrinberg Honestly, it's just what I remem,ber from astrophysics back in Uni a LONG time ago. I did a little reading to see if I was wrong and the answer seemed ambiguous. :)
