dc.descriptionIn the framework of our investigation to explain the nucleosynthesis origin of the correlated Ca-Ti-Cr isotopic anomalies in the Ca-Al-rich ''FUN'' inclusion EK-1-4-1 of the Allende meteorite, the nuclear-physics basis in the neutron-rich N=28 region has been updated by including recent experimental data on beta-decay properties and microscopic predictions of neutron-capture cross sections. Charged-particle and subsequent r-process calculations within an entropy-based approach were performed using a complete reaction network. It is shown that there exist two astrophysical scenarios within which the observed isotopic anomalies can be reproduced simultaneously; one at low entropies (about 10) which confirms the earlier suggestrd Sn Ia mechanism, and another at high entropies (about 150) which could be compatible with the neutrino-wind scenario of a SN II.
