The undated document below is available on the internet at this (link).  In summary, the paper provides numerous examples of nucleon cluster structure in light nuclei as predicted by the Brightsen Nucleon Cluster Model, including the isotopes boron-10 and lithium-7--with what is called "contribution to clustering" by helium-3 (the [PNP] cluster) and Helium-4 (the alpha).  As stated before, it is important to note that the Brightsen Model does not view helium-4 as a fundamental "nucleon cluster" building block, but instead allows for numerous combinations of 2- and 3- nucleon clusters (including matter and antimatter clusters) to form helium-4.  This is a fundamental prediction about the structure-function of helium-4 that is unique only to the Brightsen Model of the many different "cluster models" that are now known in nuclear physics.

For example, in the paper below, the nucleon cluster structure of boron-10 has been shown experimentally to contain a significant cross section of single deuteron [NP] clusters, which agrees with prediction of the Brightsen Model as discussed at the internal link What's New for 2005, ( March 29 ).  According to the Brightsen Model, one isodyne structure for boron-10 would contain two [NP] clusters in conjunction with a [NPN] cluster and [PNP] cluster.  However, the Brightsen Model also predicts that two [NP] clusters can form a single helium-4 structure (the alpha), which was also observed in the experimental results in the paper below.  This is made possible because the [NP] cluster is a "boson" and thus is not required to follow the Pauli exclusion rule, thus numerous [NP] boson clusters can coexist in the same energy shell of isotopes--exactly as predicted by the Brightsen Model.  This observation that two [NP] clusters can be found either as independent entities in the 1s shell of boron-10 each with their own quantum numbers (spin, magnetic moment, etc.) OR as a combined structure to form a helium-4 structure, is a unique prediction of the Brightsen Model.

Abstract

The use of emulsions for studying nuclear clustering in light nucleus fragmentation processes at energies higher than 1A GeV is discussed. New results on the topologies of relativistic 7Li and 10B nucleus fragmentation in peripheral interactions are given. A program of research of the cluster structure in stable andradioactive nuclei is suggested.
