In the framework of our investigation to explain the nucleosynthetic
origin of the correlated Ca-Ti_cr isotopic anomalies in the refractory
inclusion EK 1-4-1 of the Allende meteorite, beta-decay properties and
deformation of nuclear shape as well as neutron capture cross sections
of neutron-rich isotopes in the N=28 region have been determined. These
nuclear data are important input parameters for dynamic astrophysical
calculations in a complete reaction network. As astrophysical scenario a
high entropy bubble at the outer core of a type II supernova was assumed.
It will be outlined that at certain entropies between 1 and 200 k_B/Baryon
the observed Ca-Ti-Cr anomalies can be reproduced simultaneously.
