What is the problem with He-3

We consider the galactic evolutionary history of 3 in models which deplete deuterium by as much as a factor of 2 to 15 from its primordial value to its present day observed value in the ISM. We show that when 3 production in low mass stars (1 -- 3 M_) is included over the history of the galaxy, 3 is greatly over-produced and exceeds the inferred solar values and the abundances determined in galactic regions. Furthermore, the ISM abundances show a disturbing dispersion which is difficult to understand from the point of view of standard chemical evolution models. In principle, resolution of the problem may lie in either 1) the calculated 3 production in low mass stars; 2) the observations of the 3 abundance; or 3) an observational bias towards regions of depleted 3. Since 3 observations in planetary nebula support the calculated 3 production in low mass stars, option (1) is unlikely. We will argue for option (3) since the 3 interstellar observations are indeed made in regions dominated by massive stars in which 3 is destroyed. In conclusion, we note that the problem with 3 seems to be galactic and not cosmological.
