11-15 April 2022 (13-14/04 Talks)


PROGRAM  ESNT2022DynamicsBarriersF.pdf


Nuclear many-body dynamics through barriers

Organizers: C. Simenel (Australian National Univ., contact), D. Lacroix (IJCLab), D. Régnier (CEA DAM)


For detailed information, see the PROGRAM and contact the organizers (e-mail in the PDF file).



The  goals of the project are to encourage discussions and new collaborations in the following areas :


1. The description of quantum tunneling using beyond real-time-dependent mean-field techniques
2. The phenomenology of deep sub-barrier fusion and the ability of current models to predict experimental data
3. Phenomenology of potential energy surfaces (PES) topology and the role of shell effects

4. Production of improved PES for time-dependent generator coordinate method (TDGCM) calculations
5. Towards TDGCM calculations without the Gaussian Overlap Approximation

6. Interplay between internal excitations and tunneling

7. Description and interpretation of observables.


Short term visitors will be present for 5 days for collaboration purpose.

A 2 day workshop is organised on 13-14/04 with additional speakers during the same week.
