Isomeres and isotopes of carbon

2020
The nuclear geometry has been developed by analogy with the fullerene geometry. On the base of this geometric approach, the structure of carbon isomers and isotopes, which can be obtained by means of nuclear synthesis, has been designed. The mechanisms of possible nuclear reaction are discussed. Carbon is an unusual element.

Carbon isotope effects in carbonate systems

Geochimica et Cosmochimica Acta, 2004
Abstract Global carbon cycle models require a complete understanding of the δ13C variability of the Earth’s C reservoirs as well as the C isotope effects in the transfer of the element among them. An assessment of δ13C changes during CO2 loss from degassing magmas requires knowledge of the melt-CO2 carbon isotope fractionation.

Carbon Isotope Fusion

1983
The 13C + 13C total fusion cross section has been determined in the range 3.26 ≤ Ec.m. ≤ 8.0 MeV using Ge(Li) detector measurements of low-lying transitions in the residual nuclei and a statistical model calculation of excited state populations. Six different residual nuclei have been observed and their production yields are given.
