“…The method involves determining the radial overlap integral of a suitable one-particle transfer reaction, which can be parameterized using the distorted wave Born approximation and spectroscopic factors. The radial overlap function can also be described in the asymptotic limit using the Wittaker function and Sommerfeld parameter [21]. The ANC method can be extended to determine ANC's for mirror nuclei, and can be used to extract ANC's for direct capture and resonant states in nuclear reactions which is 26 Mg(p,γ) 27 Al, using data from the 26 Mg( 3 He,d) 27 Al reaction.…”

The 26Mg(p,ɣ)27Al reaction is important in nuclear astrophysics as it play a crucial role in understanding the nucleosynthesis processes in red giants and Wolf-Rayet stars. The 26Mg(p,ɣ)27Al reaction is responsible for the production of 27Al in these stars, while the 26Mg(3He,d)27Al reaction provides information on the asymptotic normalization coefficient for the ground state of 27Al.The asymptotic normalization coefficient (ANC) method is an indirect method that provides information on the normalization of the overlap functions for a given reaction. This information is crucial for nuclear astrophysics as it allows for the calculation of the direct component of the reaction rate at astrophysical relevant energies.In this work, the angular distribution of the 26Mg(3He,d)27Al reaction have been analyzed using separate sets of optical potentials via the Distorted Wave Born Approximation which allows for a better understanding of the reaction mechanism and the determination of the ANC. Consequently,thecross section and Astrophysical S factor for 27Al→26Mg + p have been calculated for the direct capture

“…In this framework, many indirect methods have been developed with the aim of measuring the bare nucleus cross section for reactions of astrophysical interest, avoiding experimental problems due to Coulomb barrier and electron screening effect. The THM has been applied in the last decades to the study of charged-particle reactions as well as neutroninduced reactions involved in several astrophysical scenarios (see [7][8][9][10][11][12][13][14][15][16][17] for recent results and reviews). THM has also been employed to study reaction induced by radioactive nuclei [18][19][20][21], expanding the THM research field to nuclear processes that take place in explosive astrophysical environments.…”

The Trojan Horse method (THM) is a well-established experimental technique to measure nuclear reactions of astrophysical interest avoiding the suppression of the Coulomb barrier affecting experimental direct measurements. In this paper it will describe some of the THM studies involving few-body system of interest for both nuclear physics and nuclear astrophysics, such as the sub-Coulomb proton-proton elastic scattering and the deuteron-deuteron fusion at energies of interest for primordial nucleosynthesis. Moreover, the role of the intercluster motion in nuclei used for THM measurement will be highlight for the discussed physics cases.

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.
