For 10 points, name these particles that comprise matter-based radiation impacting Earth.
An early paper about the interactions of these phenomena by Bhabha (BAB-huh) and Heitler put forward the "cascade" mechanism. Fleischer, Price, and Walker developed a method of detecting these phenomena using stacked Lexan poly-carbonate sheets. One facility used to observe these phenomena contains the Fly's Eye and the Surface Station; that facility is named for Pierre Auger. The AGASA (uh-GAH-sah) experiment helped find evidence of these phenomena that violate the (*) G-Z-K limit, which states that these phenomena with distant sources cannot have energy greater than 5 times 10 to 19 joules. Of the 99% of these particles that are nuclei, only 1% of them are H-Z-E ions, while over 90% are protons. For 10 points, name these particles that comprise matter-based radiation impacting Earth.
