I made an attempt at basic cleanup by adding an intro paragraph and letting the rest be in sections below. I am not a physicist however, so the efforts of anyone who can make sure I didn't oversimplify or otherwise screw it up would be appreciated. Knotnic 15:14, 23 March 2006 (UTC)
I guess I'll take a stab at this one too after I get the scattering article. The concept of event cross section isn't restricted to nuclear and particle physics. It's a much more generalized idea than that. Tarchon 00:49, 5 April 2006 (UTC)
I was doing my Physics homework and this page popped up. I noticed that it claimed the Nuclear Diameter to be 10−12 cm. Nuclear Diameter is actually measured in fm (femto-meters) which is 10−15 m, or 10−13 cm. Nuclear Radius is 10−12 cm. This unfortunatly makes the next sentence confusing: πr2 to give the correct size of a barn as 10−24 cm2 or 10−28 m2. Karplusan 03:28, 22 May 2006 (UTC)
