    Neutrino-induced nucleosynthesis and deuterium (1977)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] First, consider the conditions requisite for producing p-process nuclei from the more abundant neighbouring r- and s-process isotopes (see ref. 2 for an explanation of this nomenclature). One might invoke the charged-current processes suggested by Domogatsky and Nadozhin for producing the nucleus ...

    γ-ray bursts from thermonuclear explosions on neutron stars (1976)
    [s.l.] : Nature Publishing Group
    Nature 263 (1976), S. 101-103 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] It is proposed that γ-ray bursts originate from carbon detonations initiated by the accretion of matter on to the surface of a neutron star. The observations are interpreted in terms of this theory. Possible implications for the nuclear powered model of giant X-ray pulses are discussed ...

    Importance of isotopic composition of iron in cosmic rays (1976)
    Springer
    Astrophysics and space science 39 (1976), S. 103-121

    Notes: Abstract Measurement of the isotopic composition of iron in primary cosmic rays will yield valuable information about the site (or sites) of its production. A solar-like composition could have several explanations but even a very crude concurrent measurement of the isotopes of nickel could clarify the situation. Enhancements of54Fe or58Fe relative to56Fe would be indicative of acceleration of material from regions typically more neutron-rich than those responsible for solar abundances. Slight enhancements of54Fe could be explained by taking as a cosmic-ray source supernovae of a different typical mass or higher initial metallicity than those responsible for solar nucleosynthesis.Dominance of54Fe or58Fe would be indicative of very neutron-rich matter such as can only occur in the deep interior of a highly evolved star and would be strong evidence for the acceleration of relatively unmixed material from deep inside a supernova.
