“…A 16.3 MeV beam was delivered onto a 90% pure 17 O gas target, connected to the beam line with 3μm-thick havar entrance and exit windows. The beam energy was chosen in order to maximize the peripherical contribution of the reaction (see [10] and reference therein). The detection setup, already used in many experiments [11], consisted of 8 standard point-like ∆E-E telescopes, with thicknesses of 500μm and 5000μm, respectively.…”

Indirect methods have been established in the past as a complementary way of increasing our knowledge about nuclear structure and low-energy cross section measurements. Among these, the neutron induced reaction cross sections appear to be of particular interest because of their role both for unstable and stable beams. In view of this, we report here the combined study of the 17O(n,α)14C reaction accomplished by the Trojan Horse Method (THM) and the Asymptotic Normalization Coefficient (ANC) method. The low lying resonances 8038, 8125, 8213, and 8282 keV in 18O are studied and Γn are derived. A comparison with direct data and recent THM experimental data is presented. The independent ANC investigation corroborates our previous THM results, confirms the consistence of the two indirect investigation and shows new frontiers also in view of neutron induced reactions with RIB’s.

“…A more extended review of the method, along with a collection of remarkable results useful for astrophysics can be found in [70]. In Red Giant Branch (RGB) and AGB stars, the relevant temperatures for the 17 O and 18 O nucleosynthesis are in the ranges T 9 = 0.01-0.1 (T 9 = T/10 9 K), corresponding to an center-of-mass energy window ranging from ∼20 up to ∼150 keV.…”

Asymptotic Giant Branch (AGB) stars are among the most important astrophysical sites influencing the nucleosynthesis and the chemical abundances in the Universe. From a pure nuclear point of view, several processes take part during this peculiar stage of stellar evolution thus requiring detailed experimental cross section measurements. Here, we report on the most recent results achieved via the application of the Trojan Horse Method (THM) and Asymptotic Normalization Coefficient (ANC) indirect techniques, discussing the details of the experimental procedure and the deduced reaction rates. In addition, we report also on the on going studies of interest for AGB nucleosynthesis.

The 17O(n,α)14C reaction plays a critical role in astrophysical nucleosynthesis, particularly influencing the s-process in stellar environments. Due to the limitations of direct measurement techniques, indirect methods such as the Trojan Horse Method (THM) and Asymptotic Normalization Coefficient (ANC) analysis are employed to study this reaction at astrophysical energies. This paper discusses the application of THM and ANC to derive the reaction cross sections and explore the contributions of various resonant states of 18O. The results obtained from these indirect methods are consistent and provide new insights into the reaction mechanisms, enhancing our understanding of neutron capture processes and neutron poisons in stars. The findings also demonstrate the effectiveness of combining THM and ANC for studying neutron-induced reactions, potentially facilitating future research using Radioactive Ion Beams (RIBs). This work underscores the importance of indirect measurement techniques in advancing nuclear astrophysics, particularly where direct measurements are challenging.
