In an intense electron bombardment of the hydrogen atom, signifi cant electromagnetic radiation is produced in all directions upon decay. Which emission line would you expect to be most intense? Why?
Imagine you are a spectroscopist in 1940, looking at x-rays from a stellar object. You see a
previously undocumented x-ray with a wavelength of 0.034 nm. Assuming this to be a Ka line,
what is the atomic mass of the element that produced it?
If the mass of the electron neutrino is 2.2 eV/c2, what is the lowest temperature at which it could be formed from thermal interactions? What if its mass is 10-4 eV?
