Avril 14- Radioactive ion beam experiments and three-nucleon forces

31^st March-11^th April 2014                                         Back to the ESNT page

 

                                                                              PROGRAM    PROGram2014ESNTOxyCa3NF.pdf      

 

Organizers:  J.D. Holt (IKP, TU Darmstadt), V. Lapoux (CEA-Saclay, SPhN) and V. Somà (CEA-Saclay, SPhN).

 

 

The main goals of the project are:

 

• To examine observables (gs binding energies, matter rms radii, low-lying excited states, transition rates) for O and Ca isotopes, to make the comparison with the calculations proposing various interpretations of the shell effects;
• To compare the assumptions of the various ab-initio many-body theories: methods, specificity, limitations;
• To discuss the influence of  2N and 3N contributions and to check the sensitivity of the calculated observables to the parameters of the nuclear interactions.

In particular, the various theoretical frameworks proposed to describe the O and Ca chains will be compared.
With the experts of the field, the project will emphasize the issues related to the treatment of the 3N forces and the role played by the few-body correlations and by the tensor force in the various approaches. The influence of  the continuum of resonant, non resonant and
scattering states will also be discussed.

 

During open sessions,  informal seminars will be given, leaving time for discussions, see the details in the program file and below.

Two SPhN seminar talks are also scheduled:  

 
 Friday 4th April,  11h, Jason D. Holt,  IKP
