How was Pauling involved with the structure of the atomic nucleus?
Pauling published his Close-Packed Spheron Model of the atomic nucleus in two well respected journals.
Were his publications received well?
For nearly three decades, until his death in 1994, Pauling published numerous papers on his spheron cluster model.
How did Pauling die?
CANNOTANSWER.
Are there any other interesting aspects about this article?
The basic idea behind Pauling's spheron model is that a nucleus can be viewed as a set of "clusters of nucleons".

Question: What else can you tell me about his model?
Self-contained rewrite: Besides viewing the nucleus as a set of "clusters of nucleons, what else can you tell me about Linus Pauling's Close-Packed Spheron Model?
