Let's collect links to useful other sites here. I recently got this one to neutron capture->gamma energy data:
http://www.nndc.bnl.gov/capgam/indexbyn.html

The above would be more useful in the specific case I'm interested in if I had a link to capture cross sections too.
The site sells "the" book for $353, a bit rich for me. I'm building a directional neutron camera, and it was a bit of surprise to find out that H has a 2.2 MeV gamma on neutron capture!
However, I know it's low cross section from other sources, but not for example, enough to know whether carbon would do better for the moderator I want to use to exclude fast
neutrons from the directions the fast N sensor isn't pointed in. Most n captures result in a gamma that you then have to shield -- but if capture cross section is low enough, it won't reduce
the camera contrast too badly -- the fast N sensor (plastic scint/phototube) also sees gammas, and these hot ones need too much lead to stop.

Here's another winner:

http://www.fieldp.com/cpa.html

This is Humprhies site, and has a free download of his Principles of Charged Particle Acceleration, about 11 mb. Now this kind of academic is the sort I like -- I could host it here too, by why bother? This version is more recent than the one in our library. It's obvious this guy really knows his stuff....covers a lot of ground.

Bill has found a good book on gamma ray spectroscopy that is free. It's pretty big (over 23 megs) but probably worth getting a copy of it.
You can get it at the original source here, or off our site here.

This has some good info on taking spectra, and a catalog of spectra as well, including some complex sources like radioactive ores in equilibrium with their daughters.

Hi, To give due credit, I found it on Geo's (I think) gamma spectrometry group on yahoo. -bill

Bill found another cool link to radio-data by isotope:

Good stuff!

Bill sent this link along - some interesting yet free papers here for download
