Neutron capture reaction rates for silicon and their impact on the origin of presolar mainstream SiC grains
(2003-06)
We have made new, improved measurements of the Si28-30 (n, gamma) cross sections and have done a resonance analysis of these data including previous total cross sections. Together with the calculated contributions due to ...
s-process branchings at Sm-151, Eu-154, and Dy-163
(2001-07)
The (n, gamma) cross sections of the stable europium isotopes Eu-151 and Eu-153 have been measured by irradiating oxide samples in a quasistellar neutron spectrum. From the induced activities, the stellar cross sections ...
