International symposium: TRIP Usecase: Nuclear Transmutation 2025

10 Mar 2025, 09:00 → 12 Mar 2025, 12:30 Asia/Tokyo

RIBF bld. 2F Large Meeting Room (RIKEN)

The symposium will focus on the research topics and related issues of the TRIP use case Transmutation of elements. About RIKEN TRIP, please see https://trip.riken.jp/en/ .

The discussion will focus on two main themes. The first is the recently developing nuclear models and statistical or information-science driven approaches, which are expected to enable more quantitative descriptions and predictions of atomic nuclei. The second focus is on systematic approaches to reaction cross-section and gamma-ray measurements at RIBF.

By utilizing the acquired data, we aim to explore the data-driven and AI-driven methodologies in nuclear physics, addressing current challenges, applications to nuclear data, and future prospects. Furthermore, we will discuss strategies for nurturing the next generation of researchers in this field.

10 Statistical tools for studies of the rapid neutron capture process

Abstract:
The rapid neutron capture process (r-process) is believed to be responsible for the synthesis of the heaviest elements in the Universe and to occur in extreme astrophysical events such as compact binary mergers. Despite a multitude of efforts and developments to understand the workings of the r-process both in nuclear physics and astrophysics, many challenges and unknowns remain. One of such challenges is to quantitatively gauge our understanding of the r-process, in other words, to obtain comprehensive uncertainty estimates in the theoretical reproduction of observable quantities.

Theoretical calculations of r-process observables are known to be sensitive to the choice of nuclear physics inputs, such as mass model, beta-decay rates, neutron capture rates, fission properties, and more. Quantification and incorporation of the uncertainty of nuclear physics inputs in the r-process calculations is still a topic of active investigation. In this talk, applications of several statistical techniques to handle the uncertainty of nuclear physics inputs in the r-process studies will be discussed.
