I should like to confine this discussion of the decay of the light elements to Li, Be, and B since the observations of D and He in stars are not relevant to the decay in stellar envelopes. The light elements are trace constituents best observed in the resonance lines. Only Li I and Be II have resonance lines which can be studied from ground-based observations. Therefore we know the most about abundances in stars where these ions can be observed and how those abundances are affected by stellar evolution. I will first discuss the cosmic or initial abundances of Li, Be, and B to establish the “zero-point” from which the decay occurs. Then observations and interpretations relevant to the decay and to stellar evolution will be considered.
