abstract:

    line_1:        Boron with Li and Be is synthesized by spallation reactions between Galactic
    line_2:        cosmic rays and interstellar CNO nuclei. Theoretical predictions for
    line_3:        nucleosynthesis are close to accounting for the observed standard or cosmic
    line_4:        abundances of the trio. The 11B/10B ratio is one possible exception.
    line_6:        Observations of solar-system material give 11B/10B = 4.025, but standard
    line_7:        spallation calculations predict 11B/10B ~ 2.5.
    line_9:        HRS echelle observations of the interstellar B II 1362 A resonance line provide
    line_10:       opportunity to obtain a second measurement of the Boron isotopic ratio. The
    line_11:       1362 A line will be observed towards Kappa Ori and searched for towards 2 to 4
    line_12:       other stars.

  question:        3
    section:       1
    line_1:        All exposure involve the HRS with ECH-A at 1362.5 A. Total exposure time on a
    line_2:        single star is to be broken into smaller pieces with grating shifts to improve
    line_3:        S/N with detailed breakdown TBD.
    line_5:        Cycle 1 (SV) - No exposures
    line_7:        The primary target HD38771/Kappa Ori may be observed in cycles 2 or 3 after SV
    line_8:        tests of HRS have been published.
    line_10:       Other targets may be observed after the HD38771 data has been digested, say two
    line_11:       months.

  question:        4
    section:       1
    line_1:        Interstellar Boron is not detectable from the ground because the resonance
    line_2:        lines of the atom and ions are in the ultraviolet. The interstellar B and
    line_3:        expecially the B isotopic ratio are not predictable from the scanty imformation
    line_4:        available on interstellar Li and Be, which are also formed by spallation
    line_5:        Processes.

!

  question:        6
    section:       1
    line_1:        This program calls for high S/N spectra. I request that it not be schedule
    line_2:        until pretinent calibration data for HRS obtained in SV tests have been
    line_3:        digested by the STScI. Based on my experience with ground-based detectors, I
    line_4:        suspect that a bright star will have to be observed in order to achieve an
    line_5:        adequate calibration of the pixel-pixel variations: flat-fielding using a
    line_6:        monocromatic lamp is unlikely to yield adequate accuracy. In the event that
    line_7:        assigned to stars other than Kappa Ori. Note too that special techniques may be
    line_8:        necessary to ensure High S/N: e.g., positioning the line on the optimum portion
    line_9:        of the photocathode. It seems impossible to describe their requests now, and so
    line_10:       I have just inserted a comment on the exposure sheet.

!

  question:        7
    section:       1
    line_1:        The spectrum as reduced by the standard STScI software will be analysed at
    line_2:        the University of Texas.

  question:        10
    section:       1
    line_1:        University and Departmental computing facilities.

!

  question:        13
    section:       1
    line_1:        HRS echell spectra of the intersetellar B II 1362 A line towards Kappa Ori and
    line_2:        2 to 4 other stars will provide the isotopic 11B/10B ratio, the first
    line_3:        extra-solar-system measurement and a check on the spallation hypothesi for the
    line_4:        production of the light elements Li, Be and B.
