Odd p isotope In-113 : Measurement of alpha-induced reactions
(2009-06)
One of the few p nuclei with an odd number of protons is In-113. Reaction cross sections of In-113(alpha,gamma)Sb-117 and In-113(alpha,n)Sb-116 have been measured with the activation method at center-of-mass energies between ...
Experimental (n,gamma) cross sections of the p-process nuclei Se-74 and Sr-84
(2006-01)
The nucleosynthesis of elements beyond iron is dominated by the s and r processes. However, a small amount of stable isotopes on the proton-rich side cannot be made by neutron capture and are thought to be produced by ...
Predicted cross-sections for photon-induced particle emission
(2004-09)
Cross-sections for the photon-induced particle-emission reactions (gamma,n), (gamma,p), and (gamma,alpha) are given for all natural isotopes from Ti to Bi. The target nuclei are assumed to be in their ground states, except ...
Resonance analysis of (147)Sm(n,alpha) cross sections : Comparison to optical model calculations and indications of nonstatistical effects
(2004-01)
We have measured the (147)Sm(n,alpha) cross section from 3 eV to 500 keV and performed an R-matrix analysis in the resolved region (E(n)
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 ...
V-45(p,gamma) thermonuclear reaction rate relevant to Ti-44 production in core-collapse supernovae : General estimates and shell model analysis
(2002-07)
The lack of knowledge of the V-45(p,gamma) reaction rate has been shown to contribute a large uncertainty to the production of Ti-44 in core-collapse supernovae. By considering likely contributions from resonances associated ...
alpha- and neutron-induced reactions on ruthenium isotopes
(2002-07)
The uncertain origin of the proton rich Mo and Ru isotopes has motivated cross-section measurements of alpha- and neutron-induced reactions. The experiments were performed via the activation technique by irradiating thin ...
