  1. Alpha decay of excited states of carbon-12

    A crystal of the carbon-rich phosphor, anthracene, has been bombarded by monoenergetic fast neutrons. Alpha-particle decays of carbon nuclei have been separated from other events by a specialised application of the pulse shape discrimination technique. A numerical analysis of the data has yielded …

  3. Alpha emission from the interactions of 14-200 MeV neutrons on carbon-12

    Cross-sections for the production of alpha particles from the ¹²C(n,α)⁹Begs and ¹²C(n,n')3α reactions were measured for incident neutrons in the energy range 25 to 52 MeV. The measurements were reduced to absolute cross-sections by simultaneously observing deuteron recoils from n-d elastic …

  5. A survey of beam asymmetries in semi-exclusive electron scattering on helium-4 and carbon-12

    … in semi-exclusive ( e, e'p) reactions on 4He and 12C over a large kinematic range has been performed. The beam asymmetry A'LT is related to the imaginary part of the longitudinal-transverse interference and therefore it vanishes in reactions proceeding through a channel with a single dominant …

  6. Higher-order effects in the elastic scattering of electrons and positrons from lead-208 and carbon-12

    … sections of electrons and positrons from $\sp{12}$C and $\sp{208}$Pb, in an effort to observe and quantify deviations from the predictions of a phase shift calculation of the scattering from a static charge density. Any deviations observed can be attributed to higher-order processes sensitive …

We propose a model for the Carbon-12 nucleus based on point ↵-particles restricted to isosceles triangular configurations, inspired by linear chain and equilateral triangular Skyrmions. The configuration space is not a manifold but has a graph-like structure, and we make use …

  11. Tracking nuclear generating station emissions and fossil fuel contributions using tree rings in southern Ontario, Canada

    Changing atmospheric concentrations of stable (12C, 13C) and radioactive (14C) isotopes of carbon are an important indicator of the Anthropocene. Carbon from anthropogenic sources can be released to the atmosphere as radiocarbon (14C) from nuclear power and above-ground nuclear weapons testing. …
