Free format text (please update) We propose to use the GHRS in echelle mode to resolve the isotopic splitting of the ^11B and ^10B features at 2090Angstrom. These lines have been observed in the laboratory by one of us (Johansson) to be split by 25mAngstrom, the echelle resolution of GHRS, and we demonstrate that detection is possible. HST B obs. are now used as key data in models of galactic chemical evolution, under the assumption that the B comes from cosmic ray (CR) spallation. This is likely, but not certain (e.g. Duncan, Lambert, Lemke 1992). Woosley et al. (1990) suggest that B may be directly produced in supernovae. No simple models of galactic evolution reproduce both light element (Li, Be, and B) evolution and Fe and O evolution well at the same time. Since the predictions of spallation are quite exact as to isotopic composition, a few or even one observation of the B isotope ratio outside the solar system (the only place ^11B/^10B has been observed) would be an enormous help to constrain theory. A similar detection has been achieved by one of us (Thorburn) for the isotope ^6Li in a halo star. Our program is carefully optimized as to target stars. Since the solar system ^11B/^10B ratio does not match theory, we suggest (first) observing bright solar- metallicicty and intermed metal-poor stars. There high S/N can be achieved and B isotope ratio is predicted to have a large change. More metal-poor stars should follow. Questions ! Free format text (please update) Observing_Description: ONE OBJECT WAS DISALLOWED. NOW THERE ARE TWO: All three objects have been extensively observed by IUE near 2090Angstrom and by HST at other wavelengths. The fluxes near 2090Angstrom are well known and the exposure times relatively precise. For example, we scaled the exposures of HD76932 from our own GHRS med. resolution observations near 2500Angstrom by the ratio of the different grating sensitivities at the different wavelengths, to achieve S/N ~ 110.
