“…Due to the astrophysical interest, the laboratory (α,γ) reaction cross section on the nucleus 112 Sn has been measured [16] at energies close to the Gamow window. The astrophysical S-factor of the reaction 112 Sn(α,γ) 116 Te is shown in Fig.…”

“…Because of the scarce experimental data available on the 112 Sn(α,γ) 116 Te reaction, we can only perform a very limited comparison. Ozkan et al [16] McFadden/Satchler [22] Demetriou et al [23] Avrigeanu et al [24] Frohlich/Rauscher [25] This work The global parameterization from [25] provides a satisfactory description of the few experimental data, in contrast to its poor agreement with the elastic scattering data. The other potentials, with the exception of [24], reproduce the cross section data well.…”

“…However, there is still a lack of relevant experimental data for (γ,α) and (α,γ) reactions because of the high Coulomb barriers. Recent α capture experiments on heavy nuclei at astrophysically relevant energies were performed on 70 Ge [14], 96 Ru [15], 112 Sn [16] and 144 Sm [17]. No experimental data for (γ,α) cross sections are available at astrophysically interesting energies.…”

The cross sections for the elastic scattering reactions 112,124 Sn(α,α) 112,124 Sn at energies above and below the Coulomb barrier are presented and compared to predictions for global α-nucleus potentials. The high precision of the new data allows a study of the global α-nucleus potentials at both the proton and neutron-rich sides of an isotopic chain. In addition, local α-nucleus potentials have been extracted for both nuclei, and used to reproduce elastic scattering data at higher energies. Predictions from the capture cross section of the reaction 112 Sn(α,γ) 116 Te at astrophysically relevant energies are presented and compared to experimental data.

“…The corresponding cross section, calculated with the TALYS reaction code [17], is between 10 −8 and 10 −3 b respectively. The bulk of (p,γ ) measurements have been performed in the lower mass region (A < 112) [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36], except for 120 Te [37], 130 Ba [38], and 152 Gd [39]. For the (p,n) channel, very few (p,n) measurements have been performed, with the exception of 76 Ge [20], 82 Se [21], 85 Rb [34], 120 Te [37], 130 Ba [38], and 152 Gd [39].…”

It is crucial to measure reaction cross sections relevant to the astrophysical γ process so that theoretical reaction rates can be tested and validated with experimental data. The total cross sections for the 162 Er(p,γ ) 163 Tm and the 162 Er(p,n) 162 Tm reactions have been measured by the activation method in center-of-mass energies from 3.973 to 8.944 MeV and from 5.962 to 8.944 MeV, respectively. The nucleus 162 Er is the heaviest p nuclide to be measured by the activation method using γ -ray spectroscopy, so far. It is important to note that the energy range for the (p,γ ) reaction measurement covers a large fraction of the astrophysically relevant energy region between 2.71 and 5.34 MeV. The targets were prepared by evaporating 28.2% isotopically enriched 162 Er 2 O 3 powder onto carbon backing foils, and bombarded with proton beams provided by the FN Tandem Accelerator at the University of Notre Dame. The reaction yields have been determined by the observed activity of produced radioactive isotopes, which was detected offline by a high-purity germanium detector. The results are presented and compared with calculations from two statistical model codes: NON-SMOKER and TALYS.

Expanding Nuclear Physics Horizons with the Gamma Factory

The Gamma Factory (GF) is an ambitious proposal, currently explored within the CERN Physics Beyond Colliders program, for a source of photons with energies up to ≈400 MeV and photon fluxes (up to ≈1017 photons s−1) exceeding those of the currently available gamma sources by orders of magnitude. The high‐energy (secondary) photons are produced via resonant scattering of the primary laser photons by highly relativistic partially‐stripped ions circulating in the accelerator. The secondary photons are emitted in a narrow cone and the energy of the beam can be monochromatized, down to 10−3–10−6 level, via collimation, at the expense of the photon flux. This paper surveys the new opportunities that may be afforded by the GF in nuclear physics and related fields.
