It is known that a spectral line lambda= 612nm of an atom is caused by a transition between singlet terms. Calculate the interval Delta lambda between the extreme components of that line in the magnetic field with induction B=10.0KG. |

Answer» SOLUTION :As the spectral line is caused by transition between singlet terms, the `Z` eeman effect willl be normal (since `g=1` for both terms). The energy DIFFERENCE between extreme COMPONENTS of the line will be `2mu_(B)B`. This MUST equal `-Delta((2piħc)/(lambda))=(2piħc Delta lambda)/(lambda^(2))` Thus `Delta lambda=(mu_(B)Blambda^(2))/(piħc)=35 p m`. |
