dc.description.abstractProton bombardment of the solar nebula is investigated as a means for the production of observed meteoritic anomalies in the elements neon and magnesium. Condensation of nebular gas during the irradiation provides the means for transporting 26Al and 22Na formed in the gas to the solid 26 22 phase where decay to Mg and Ne occurs. Each element is assigned an independent condensation rate, and isotopic ratios in both the gas and condensing solid are monitored. Results indicate that it is possible to specify a set of parameters that would produce the observed anomalies in both 26Mg and 22Ne without disturbing other isotopic ratios. The required condensation rates seem to agree with current models of the condensation of a cooling gas of cosmic composition. In addition, the irradiation model is capable of producing the negative 2 6Mg anomalies that have currently been deduced from the analysis of meteorite inclusions.en_US
