  1. 33. The Big Three Reaction for Nuclear Astrophysics: the forthcoming workshop in Strasbourg
    Dr Roberta Sparta' (Istituto Nazionale di Fisica Nucleare)
    22/02/2024, 13:50

    A forthcoming workshop (29th May) will be held in Strasbourg also in the context of the ChETEC-INFRA project, to discuss the The Big Three Reaction for the nuclear astrophysicists community. The main goal of the workshop is to network the existing and forthcoming research programs around the 12C(α,γ), 12C+12C and 22Ne(α,n) fusion reactions

    This study presents accurate and high-resolution measurements of the 25Mg(n,γ)26Mg and 25Mg(n,tot) cross sections, from thermal energies up to approximately 300 keV. Through a combined R-matrix analysis of the experimental data, the pertinent neutron resonances for the interaction with 25Mg were characterized. Consequently, this analysis led to an improved set of reaction widths, along with a...

  7. 26. Re-evaluation of the 22Ne+alpha reaction rates
    Dr Philip Adsley (IPN Orsay)
    22/02/2024, 17:00

    There has been a large amount of new nuclear data on the 26Mg compound system, some of which we will discuss at this workshop. Combining these data into reaction rates requires dedicated work to combine the different data, resolve discrepancies and provide updated estimates with, if possible, well-motivated uncertainties. In this talk, I will discuss some of the indirect measurements which...
