Nucleon Cluster Structures in Isotopes

[Rade]

I would like to start a thread on this topic--nucleon clustering phenomena in isotopes. I wish to learn the status of current research in this area. I cite a few publications on the topic below. For example, who today applies quark theory to John Wheeler (1937--see below) concept of "resonating group structures" ? If not, why not ?
