    • Analytical Absorption Cross-Section for Photon by a Hydrogen 2s Atom 

      Boniface Otieno Ndinya, Stephen Onyango Okeyo (IOP Publishing, 2011-04)
      We calculate the absorption cross-section for photon by a hydrogen 2s atom using the quantum-classical approximation for the total photo cross-section of many electron atoms. With the application of the first-order term ...
