OTHER MEETINGS/WORKSHOPS/PROGRAMS2012 FUSTIPEN Fission Workshop On January 4-6, 2012, we coorganized Topical Meeting on "Theory of Nuclear Fission in GANIL, Caen, France. The program of the workshop can be found here. During September 23-November 15, 2013, we run a program on Quantitative Large Amplitude Shape Dynamics: fission and heavy ion fusion at the Institute for Nuclear Theory, Seattle. The intent of this program was to: (i) bring together theorists working on predictive theories of the underlying shape dynamics to compare various approaches and computational methodologies; (ii) actively foster collaborations between the major actors in the field, including collaborations between experiment and theory; (iii) identify critical experimental data that will inform theoretical developments; and (iv) identify strategies and resources to break computational barriers in this area. We believe that excellent progress has been made in all four areas. The program was well attended, with 65 total participants. Week 4 of the program was organized as predominantly experimental workshop, which dealt largely with new data on fission and fusion to challenge nuclear theory. The talks at INT-13-3 can be found here. The program needs to be put into the perspective of the intellectual development that occurred since the last INT program on large-amplitude dynamics, INT-95-3 (organized by Bertsch and Nazarewicz). As presented in the talks, we now have accurate descriptions (< 1 MeV) of fission barriers based on self-consistent mean-field theory, with the beginnings of systematic error assessments of the theory. Quantitative results are now available the calculation of heavy-ion fusion cross sections by TDHF. The calculations of spontaneous fission lifetimes have become much more sophisticated in the context of the WKB barrier penetration model: more collective degrees of freedom are taken into account in setting the fission path; the path may now be determined by minimizing the action; the inertia term in the action integral may be treated in a way consistent with the instanton formulation of barrier penetration. We also saw a major advance in the theory of fission mass distributions: many of the details can be reproduced by a statistical treatment with diffusive dynamics. We expect that new experimental efforts discussed during the program will not only greatly increase the database for which current theory can be applied but will also provide its crucial tests. A reporting guide has been prepared for theorists to make it easier to compare different methods and to assess the reliability of theory for applications. The guide includes the list of measured/evaluated quantities (spontaneous fission half-lives, fission barrier heights, fission fragment mass distributions, and excitation energies of fission isomers) that can be used to benchmark various methodologies and optimize models. Another guide gives recommendations on error analysis of the theory and how to present the uncertainties.Information and statistics in nuclear experiment and theory On November 6-9, 2017, we coorganized ISNET-5 meeting in York, UK. The aim of this series of workshops - involving the broad nuclear physics community, together with applied mathematics, statistics and computer science - is to discuss the use of applied mathematics, information theory and statistics in the analysis of experiments, and within the context of theoretical models that are dealing with current and future experimental data. Previous ISNET meetings have been held in Krakow, Poland (2012); Glasgow, UK (2013), ECT* (2015) and INT (2016). On Oct 14-16, 2019 we helped organizing nuclear fission theory meeting in York, UK. The promising new theoretical avenues were discussed. The resulting report summarises its findings and recommendations. |
