24 October-1st November 2015
PROGRAM 
ProgramESNTCalc3n4n_Oct15.pdf
Organizers : Jaume Carbonell (IPNO), Rimantas Lazauskas (IPHC) and Emiko Hiyama (RIKEN)
ESNT Visitors ESNT associated to the project : R. Lazauskas and E. Hiyama
The 4-body problem will be reconsidered in a common work, and the main objective of the project is try to draw some conclusions about the eventual observation of the 4n resonances, at least from the perspective of the theoretical nuclear physics.
The goals of the project are to:
1. Compute using two independent methods (Faddeev-Yakubovsky and Variational Gaussian basis) the position
of 3n and 4n resonances in the complex energy plane;
2. Study the eventual experimental signature of these states.
