Question

12pts) Some measured X-ray energies in an element are ∆E(Kα)= 20.00keV and ∆ E(Kβ)= 25.00 keV.
The binding energy of the K electron in the element is E(K)=26.00keV. From these data, find:

(a) the energy of the Lα X ray, and

(b) the binding energy of the L electron

Answer 1

Given that a let us consider, X-ray energia in an Element are DE Cka) 20.00 ke v DECKB) = 26.00 kev The binding Energy of the k Electron Element is in the ECC) = 26.00 lcev The Energy of the Le X-ray. let, DE CLd) DECKB)- DE Cka) =Q5-20) Icev DE (La) - 5 kev The binding energy of the election.
