Determination of (n,gamma) reaction rates at s-process branching points via their inverse reactions
(2003-05-19)
We present our method to determine the (n,gamma) reaction rates of s-process branching point nuclei using data of the inverse (gamma,n) reaction. As an example, we selected Zr-95. The analysis of the data of the reaction ...
Determination of the (n,gamma) reaction rate of unstable W-185 in the astrophysical s-process via its inverse reaction
(2003-05-05)
The (gamma,n) reaction rate of W-186 was measured in order to deduce the (n,gamma) reaction rate of 185 W, an important branching point in the astrophysical s-process. The theoretical predictions have been confirmed and ...
The s-process branching at W-185
(2003-01-20)
The neutron capture cross section of the unstable nucleus W-185 has been derived from experimental photoactivation data of the inverse reaction W-186(gamma, n) W-185. The new result of sigma = 687 +/- 110 mbarn confirms ...
