Scientific paper

The Nuclear Astrophysics Explorer was proposed for NASA's Explorer Concept Study Program by an international collaboration of 25 scientists from 9 institutions. The proposal was accepted and a one year study began in June 1988. The Nuclear Astrophysics Explorer would obtain high resolution observations of gamma-ray lines, E/ΔE~1000, at a sensitivity of ~3×10-6 ph/cm2-s, in order to study fundamental problems in astrophysics such as nucleosynthesis, supernova dynamics, and neutron star and black hole physics. The instrument would operate from 15 keV to 10 MeV and use an array of cooled Ge spectrometers in a very low background configuration. A 10° FWHM field of view would contain a versatile coded mask system which would provide 4° imaging and the ability to efficiently measure diffuse emission and study it with 2° resolution.
