PROGRAM

 

Experimental and Theoretical Aspects of Neutron-Proton Pairing and Quartet Correlations in Atomic Nuclei

 

 

Organizers:   

Augusto O. Macchiavelli (Oak Ridge National Lab., contact), Nicolae Sandulescu (IFIN-HH, National Institute of Physics and Nuclear Engineering ; contact )
  

 The two previous ESNT workshops on np pairing have been mainly focused on the theoretical perspective, having in depth discussions on recent developments, in particular on the mean field description of np pairing and on the role of alpha-like quartets in N=Z nuclei.

In this workshop we will direct our attention to review the most recent experimental studies on np and quartet correlations, with the goal of reaching a consensus between theorists and experimentalists on what the (limited) body of available data is telling us about deuteron like pairing and the emergence of alpha-like quartet correlations and clustering.

 

The goals of the workshop are:
 

1. To review the most recent experimental studies on np pairing and quartet correlations.
2. To present new theoretical developments related to the topic.
3. To discuss possible experimental probes to further assess the nature of np correlations and the relevance of alpha-like degrees of freedom and clustering in nuclei, including super-allowed alpha decay and delayed alignment in N=Z nuclei.
