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.
