WebCompton effect: Occurs at medium energies (.5 - 5 MeV); incoming photon ejects an electron and a photon with longer wavelength. Pair production: Requires high energies ( > 1.02 MeV, usually > 5 MeV); incoming photon ejects an electron and a positron, but positron quickly encounters an electron and annihilates to two 0.51 MeV gamma rays (E=Mc 2). Web(a) The average atomic mass of naturally occurring neon is 20.18 amu. There are two common isotopes of naturally occurring neon as indicated in the table below. Isotope Mass (amu) Ne-20 19.99 Ne-22 21.99 (i) Using the information above, calculate the percent abundance of each isotope. Let xrepresent the natural abundance of Ne-20.
