Assuming there aren't any actual nuclear physicists on INTPC, I'll ask if anyone knows a really good resource which states the requisites, such as temperature and/or pressure, for fusion of such atoms as...Deuterium.

Leave Hypnos a PM. He might know. He still checks in now and then, even though he's technically left the board.

I've already searched my ass off. No luck so far with the hard data I'm interested in.

What about google scholar, or a system similar to Athens that we have at my uni?

Too much tech, not enough physics, same same.

I only know anecdotal stories like how many cords of seasoned oak are required.

Maybe this?

Nice, but all about plasma (thermonuclear). I think it's a wash. I'm gonna have to dust off some books from the 50s or something.

3,000,000 K to fuse hydrogen. 300,000,000 K to fuse helium. If a stellar core does not reach above 3,000,000 K, fusion will never occur, and the star will be a brown dwarf.

Doing the calculations to determine temperatures for fusing things is a pain in the ass, because quantum tunneling is involved. Were it not for tunneling, the temperature required to get two protons close enough together to where the strong nuclear force is pulling them together harder than the Coulomb force is repelling them would be far higher than the temperature in the core of the sun (or virtually any star, if memory serves).

It's entirely possible the information you seek can be found in this book (http://www.amazon.com/gp/product/0805304029/sr=8-2/qid=1148036713/ref=pd_bbs_2/002-4817812-7187205?%5Fencoding=UTF8). Or maybe this one (http://www.amazon.com/gp/product/0226109534/ref=pd_sim_b_3/002-4817812-7187205?%5Fencoding=UTF8&v=glance&n=283155) or even this one (http://www.amazon.com/gp/product/0486614794/sr=8-7/qid=1148037087/ref=sr_1_7/002-4817812-7187205?%5Fencoding=UTF8).
