Abstract
A simple picture is outlined which can account for the new boron abandance in the meteorites (B/H ~ 10/sup -8/following Cameron et al.) together with lithium and beryllium. /sup 11/B, /sup 10/B, and /sup 7/Li are pro duced by large fluxes of low-energy particles (~ 10 MeV particles) accelerated by shock waves occurring in supernovae envelopes while /sup 6/Li and /sup 9/Be are produced by the high-energy cosmic rays impinging on the interstellar gas.
