SUMMARY
The discussion focuses on determining the constant A and identifying the atom based on spectral lines at wavelengths λ1=97.5 nm and λ2=102.8 nm. Participants confirm that the atom is likely either Hydrogen or Li++, with the energy levels described by the formula E_n=-A/n^2. The correct value of A for Hydrogen is established as 13.6 eV, while for Li++, the value must account for the increased nuclear charge, leading to a different A value. The Rydberg formula is suggested as a method to find the transitions corresponding to the observed wavelengths.
