“…The cross section determination is based on a comprehensive R-matrix analysis including representative sets of 10 B(p,α) 7 Be data and also includes data for complementary reaction channels such as radiative capture 10 B(p,γ) 11 C and elastic scattering 10 B(p,p) 10 B as described by [14]. Through this self-consistent application of the phenomenological R-matrix theory [13], a reliable extrapolation over the entire energy range with relative small uncertainty has been achieved [43,25].…”

“…Despite these low energy measurements, the cross section at the energies of inertial confinement fusion facilities still is rather uncertain. For example, Spitaleri et al [25] quotes a low energy uncertainty of between 10 and 20%. While the data of Angulo et al [22] have rather small error bars, the data also show a significant amount of scatter, indicating the presence of significant non-statistical uncertainties.…”

The typical energy range for charge particle interactions in stellar plasmas corresponds to a few 10s or 100s of keV. At these low energies, the cross sections are so vanishingly small that they cannot be measured directly with accelerator based experimental techniques. Thus, indirect studies of the compound structure near the threshold are used in the framework of reaction models to complement the direct data in order to extrapolate the cross section into the low energy regime. However, at the extremely small cross sections of interest, there maybe other quantum effects that modify the such extracted cross section. These may result from additional nuclear interactions associated with the threshold itself or could be due to other processes, such as electron screening. Measurements in plasma environments like at the OMEGA or National Ignition Facility facilities offer an entirely new set of experimental conditions for studying these types of reactions, often directly at the energies of interest. In this paper, we examine three reaction, 10B(p,α)7Be, 12C(p,γ)13N and 14N(p,γ)15O, which have all been measured at very low energies using accelerator based methods. All three reactions produce relatively long-lived radioactive nuclei, which can be collected and analyzed at plasma facilities using a variety of collection and identification techniques.

“…Therefore, the investigation of the origin of stars and related phenomena dials closely with plasma physics. Moreover, the measurements of nuclear reaction rates and theoretical estimations in order to understand the origin of the chemical elements and the energy generation in stars is possible thanks to Nuclear Astrophysics [1][2][3]. For this reason, the study of laser produced plasmas could be important for nuclear astrophysics implications [4].…”

“…In this context, also the study of non-self-conjugate nuclei is of noticeable importance because of the role played by extranucleons in modifying the α cluster structure [14][15][16][17][18][19][20][21][22]. However, if compared to the case of self-conjugate nuclei, this type of experimental investigations is made difficult by the presence of nucleon-decay channels that are open at low energies and, in general, by the presence of a high-level density [23].…”

In this work we reinvestigate the spectroscopy of 13 C at excitation energies larger than the α emission threshold (E x > 10.648 MeV) by means of a comprehensive R-matrix fit of experimental data concerning α + 9 Be collisions at low energies. Owing to the analysis of many reaction channels in a broad energy range, we improved the current knowledge on the level scheme of 13 C, by contributing to remove uncertain J π assignments for several states. Some tentative speculations on the existence of molecular bands associated to cluster structures in this nucleus are also discussed.
