Sp-process and Allende isotope anomalies in calcium and titanium

Slow proton captures (on a time scale >> weak-interaction time scales) on 18< or =Z< or =25 nuclei at temperatures in the range 1.25< or =T9< or =1.7 can reproduce the Ca isotope anomaly in Allende Ca-Al--rich FUN inclusion EK--1--4--1. At T9 = 1.55 the required proton exposure approximately reproduces the EK--1--4--1 Ti anomaly also. Under these conditions the production of long-lived 41Ca and 53Mn and of an anomaly in Cr is predicted
