  Light element nucleosynthesis is an important chapter of nuclear
astrophysics. Specifically, the rare and fragile light nuclei Lithium,
Beryllium and Boron (LiBeB) are not generated in the normal course of stellar
nucleosynthesis (except Li7) and are, in fact, destroyed in stellar interiors.
This characteristic is reflected in the low abundance of these simple species.
Optical measurements of the beryllium and boron abundances in halo stars have
been achieved by the 10 meter KECK telescope and the Hubble Space
Telescope.These observations indicate a quasi linear correlation between Be and
B vs Fe, at least at low metallicity. Aside GCRs, which are accelerated in the
general interstellar medium (ISM) and create LiBeB through the break up of CNO
by fast protons and alphas, Wolf-Rayet stars (WR) and core collapse supernovae
(SNII) grouped in superbubbles could produce copious amounts of light elements
via the fragmentation in flight of rapid carbon and oxygen nuclei colliding
with H and He in the ISM.
