The effects of crystal field on Nd(su3+) in the laser host YVO(in4)

The behavior of Nd³⁺ in the laser host yttrium orthovanadate, YVO₄, has been investigated with respect to its absorption spectra By taking into consideration intermediate coupling, a new set of crystal field parameters is obtained which gives a lower rms deviation between observed and calculated energies for 25 of the 26 levels of the ⁴I term than that reported earlier using a pure Russell-Saunders basis. The computed g-factors are also in good accord with resonance results Vanous quantities including the nuclear hyperfine parameters have been calculated Nuclear properties which depend on the crystal field are predicted for both the isotopes of Nd
