1) One line in the line spectra for Li (Z=3) is produced by a transition from electron initial state 3d to a final state 2s.
a)What are the possible quantum numbers for the initial state?
b)What are the possible quantum numbers for the final state?
c)What is the wavelength of the spectral line produced by this transition?
d)What is the change in orbital angular momentum in this transition?
2) In an X-ray tube filled with Pt (Z=78) is a voltage of 60kV large enough to produce Ka X-rays? What is the minimum voltage needed?
