Proton−90Zr interaction at sub-Coulomb proton energies

p-process nucleosynthesis via proton-capture reactions in thermonuclear supernovae explosions

“…These values could be confirmed by a 4π in-beam summing crystal measurement by A. Spyrou et al [14]. Nevertheless, a measurement using γ-ray spectroscopy by C. E. Laird et al disagrees with the two other data sets for the total cross section [15]. In order to solve this discrepancy, we measured this reaction again using high-resolution in-beam γ-ray spectroscopy.…”

Measurements of proton-induced reaction cross sections onTe120for the astrophysicalpprocess

“…The last decade has seen an increased interest in measuring the proton capture cross sections of p-nuclei [10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25]. The bulk of these (p,γ) measurements have been done in the lower mass region (A < 100).…”

“…Variations can lead to substantial changes in p-process abundance predictions. There is considerable effort to experimentally test the reliability of p-process predictions on selected cases [6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25]. Since the photodisintegration process 121 I(γ, p) directly feeds 120 Te, this reaction provides an excellent case for testing the reliability of the Hauser-Feshbach prediction near the closed proton shell Z=50; 121 I has a high level density near the proton threshold and the reaction should be eligible for the statistical model prediction [26].…”

The [sup 85]Rb(p,n)[sup 85]Sr reaction and the modified proton optical potential

“…The relevant astrophysical reaction rates can be determined from the cross section of the inverse capture reactions through the detailed balance theorem if the corresponding capture cross sections are known experimentally. In the last few years several proton capture cross section measurements for p process studies were carried out [5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]. However, it has been shown recently that not only (γ,p) reactions are important for modeling the synthesis of the light p nuclei, but (n,p) and (p,n) reactions should also be taken into account [4].…”
