dc.description.abstract | This work reports on accurate, high-resolution measurements of the 25Mg()26Mg and 25Mg() cross sections in the neutron energy range from thermal to about 300 keV, leading to a significantly improved 25Mg()26Mg parametrization. The relevant resonances for Mg were characterized from a combined R-matrix analysis of the experimental data. This resulted in an unambiguous spin/parity assignment of the corresponding excited states in 26Mg. With this information experimental upper limits of the reaction rates for 22Ne()25Mg and 22Ne()26Mg were established, potentially leading to a significantly higher ratio than previously evaluated. The impact of these results has been studied for stellar models in the mass range 2 to 25 . | en_AU |
