Report

Impact of the $^6$Li asymptotic normalization constant onto $\alpha$-induced reactions of astrophysical interest

Autor: Hebborn, Chloë, Avila, Melina L., Kravvaris, Konstantinos, Potel, Gregory, Quaglioni, Sofia

Publikováno v: Phys. Rev. C 109, L061601 (2024)

Indirect methods have become the predominant approach in experimental nuclear astrophysics for studying several low-energy nuclear reactions occurring in stars, as direct measurements of many of these relevant reactions are rendered infeasible due to

Study of the $^{22}$Mg waiting point relevant for x-ray burst nucleosynthesis via the $^{22}$Mg($\alpha$,$p$)$^{25}$Al reaction

Autor: Jayatissa, H., Avila, M. L., Rehm, K. E., Mohr, P., Meisel, Z., Chen, J., Hoffman, C. R., Liang, J., Müller-Gatermann, C., Neto, D., Ong, W. J., Psaltis, A., Santiago-Gonzalez, D., Tang, T. L., Ugalde, C., Wilson, G.

The $^{22}$Mg($\alpha$,$p$)$^{25}$Al reaction rate has been identified as a major source of uncertainty for understanding the nucleosynthesis flow in Type-I x-ray bursts (XRBs). We report a direct measurement of the energy- and angle-integrated cross

Probing the quadrupole transition strength of 15C via deuteron inelastic scattering

Deuteron elastic scattering from 15C and inelastic scattering reactions to the first excited state of 15C were studied using a radioactive beam of 15C in inverse kinematics. The scattered deuterons were measured using HELIOS. The elastic scattering d

Classification of events from $\alpha$-induced reactions in the MUSIC detector via statistical and ML methods

Autor: Raghavan, Krishnan, Avila, Melina L., Balaprakash, Prasanna, Jayatissa, Heshani, Santiago-Gonzalez, Daniel

The Multi-Sampling Ionization Chamber (MUSIC) detector is typically used to measure nuclear reaction cross sections relevant for nuclear astrophysics, fusion studies, and other applications. From the MUSIC data produced in one experiment scientists c

Report

First direct measurement of the $^{13}$N($\alpha$,$p$)$^{16}$O reaction relevant for core-collapse supernovae nucleosynthesis

Autor: Jayatissa, H., Avila, M. L., Rehm, K. E., Talwar, R., Mohr, P., Auranen, K., Chen, J., Gorelov, D. A., Hoffman, C. R., Jiang, C. L., Kay, B. P., Kuvin, S. A., Santiago-Gonzalez, D.

Publikováno v: Phys. Rev. C 105, L042802 (2022)

Understanding the explosion mechanism of a core-collapse supernova (CCSN) is important to accurately model CCSN scenarios for different progenitor stars using model-observation comparisons. The uncertainties of various nuclear reaction rates relevant
