Unformatted text preview: between levels of 0.20 eV. Assume the dipole to be eX. Use cgs units. 3) Determine the 1s <> 2p absorption, stimulated emission, and spontaneous emission rates (s1 ) for H atoms in the solar photosphere (T = 6000 K). Which is the larger emission rate? 4) Use Fermis Golden Rule for timeindependent perturbations to derive the Born Approximation for elastic collisions. Use box normalization. Your final result should be: ( ) = 2 4 2 h 4  exp(i { k fk i } r ) V ( r ) d  2...
