Three curves of stability?

[Goccam]

I've been doing some analysis on isotope data for a paper, and I've obtained some results which dont seem to appear in the literature. Have you come actross this?

Here's the first one.

I haven't seen it, but I would be surprised if it is new. That the odd and even nuclei act differently is well known, for example see:

I don't remember seeing the two types of even being different, but this is not my field. I would be stunned if it wasn't done already.
