Reaction rate sensitivity of Ti-44 production in massive stars and implications of a thick target yield measurement of Ca-40(alpha, gamma)Ti-44
(2010-06-01)
We evaluate two dominant nuclear reaction rates and their uncertainties that affect Ti-44 production in explosive nucleosynthesis. Experimentally we develop thick target yields for the Ca-40(alpha, gamma)Ti-44 reaction at ...
Stellar (n,gamma) cross sections of p-process isotopes Part I: Pd-102, Te-120, Ba-130,Ba-132, and Dy-156
(2010-01)
We have investigated the (n,gamma) cross sections of p-process isotopes with the activation technique. The measurements were carried out at the Karlsruhe Van de Graaff accelerator using the Li-7(p, n) Be-7 source for ...
