# Isotope properties plotting tool?

I'm looking for something that will generate scatter plots comparing different properties of isotopes. Ideally I'd like some web page that lets me select axis and click go but a CSV file with lost of properties would work.

This seems like the kind of question to ask on the webapps SE. But I guess it could go here too... (admittedly there probably aren't that many people on webapps.SE who are familiar with nuclear physics) –  David Z Dec 8 '10 at 5:46
@David: First, I also thought that this is off-topic but now (after exchanging few comments with Frédéric and looking at some other software questions) I tend to think that it is fine (especially considering the software tag). Also, there is the reason you stated: this probably wouldn't get answered anywhere else. –  Marek Dec 8 '10 at 11:06
I chose to post it here because primarily the question is about the data set and secondarily about the tooling. –  BCS Dec 8 '10 at 15:32

Exploring the Table of Isotopes is my go-to site.

There are a few others out there, but when I moved from my last computer those were some of the bookmarks I didn't bring, 'cause I never used them...

You haven't specified what you want in your CVS file. I think this site only offers transition energies and branching fractions by radiation type.

For searching a whole database of transistions for lines of [energy range]$\times$[A or Z range]$\times$[halflife range] use The Lund/LBNL Nuclear Data Search. Very useful if you are thinking of building a novel calibration source or some thing like that. This site also has stopping powers and other good stuff (go up a level from the link...). Another go-to resource.

What I was hoping to do was plot N vs λ. The spesific problem I'm interested in is what's with the bite mark in this chart at N~=130?: en.wikipedia.org/wiki/File:Isotopes_and_half-life.svg –  BCS Dec 8 '10 at 2:33
