dc.description.abstractA detailed study of hyperfine structure observed in the 0,0 band of the 3Φ (aβ) →3Δ (aβ) system of NbN has shown that the secondary hyperfine effects observed in this structure are not due to a perturbation in the 3Δ state but rather to the presence of a nonnegligible hyperfine effect in the 3Φ excited state. Calculations of the intensity factors corresponding to the observed transitions confirm this hypothesis and give results in excellent agreement with experiment.en_US

dc.identifier.citedreferenceThe positions were calculated approximating the Hamiltonian for the 3Φ23Φ2 state by T0Φ+BΦ2J(J+1),T0Φ+BΦ2J(J+1), while that for the 3Δ13Δ1 was T0Δ1+BΔ1J(J+1)+Hhfs±HΛdoub.T0Δ1+BΔ1J(J+1)+Hhfs±HΛdoub. These approximations are sufficient for a study of the five first lines in each substate.en_US

dc.identifier.citedreferenceThe experimental densities are of the form d  =  α logIt+β′d=αlogIt+β′ where t is the exposure time and I is the intensity, proportional to the Boltzman factor which depends upon J and on the intensity factor f, calculated in the Appendix. The Boltzman factor is almost constant over the range of our study and we may then write d  =  α logf+β.d=αlogf+β. To take the response of the plate into account, the lowest intensity lines were not measured. Their positions are indicated by ••. For the other lines, the bar height is proportional to logf.en_US
