On behalf of the “Espace de Structure et de réactions Nucléaires Théorique” (ESNT), the workshop entitled: “Towards high precision in multi-channel reactions of composite nuclei” will be held at CEA-Saclay, Orme-des-Merisiers site (room 135) from 29th June till 10th July.
Talks and seminars are organized during the first week (29/06 – 03/07). The second week corresponds to the working group closed sessions.
Low-energy reactions of composite nuclei are relevant for both technical and basic-science applications, and it remains a fundamental problem to reduce the uncertainties in their theoretical description. These uncertainties originate in a complicated interplay between strong and electromagnetic interactions at the low energies of interest where neither of the two can be neglected.
This project is held at a period at which the organizers deem the advancement in numerical techniques and algorithms, and the understanding of refining the nuclear interaction systematically sufficient to explore with reliable error estimates many ideas and hypotheses on how to affect reaction cross sections. To be specific in their goal, the organizers of the working group aim for theoretical predictions of reaction cross sections of composite nuclei with nucleons as degrees of freedom. Projectiles, targets, and reaction products are thus few-nucleon systems, and their formation in asymptotic states, their distortion and rearrangement in the collision process shall all be described with the same nuclear theory.
Amongst the goals of the project, experimentalists and theoreticians shall identify key reactions:
[i] to benchmark the accuracy of the numerical methods employed, i.e., a list of reactions measured with high precision,
[ii] to test the usefulness of interaction theory and numerical methods, i.e., reactions whose measurements are imprecisely known experimentally, and
[iii] to propose future experiments where the framework to be developed can demonstrate its predictive power and trustworthiness for applications in astrophysics, fusion research, and other fields where experiments are either unfeasible or too costly.
