Energy Levels of Tetragonally Sited $\Pr^{3 +}$ Ions in Calcium Fluoride Crystals

The crystal-field-split levels of tetragonally sited

\Pr^{3 +}

ions in calcium fluoride crystals have been experimentally determined and the crystal field constants have been calculated as

B_{0}^{2} = 500

B_{0}^{4} = - 350

B_{0}^{6} = 600

B_{4}^{4} = 200

, and

B_{4}^{6} = 550

. From center-of-gravity values of the experimental levels, and using a constant electrostatic depression of 1200

{cm}^{- 1}

for all levels with energies over 10 000

{cm}^{- 1}

, the multiplet-level solution has been determined as it exists in the crystal field. Parameters determined for that multiplet solution are

F_{0} = 13828

F_{2} = 324

F_{4} = 58.0

F_{6} = 6.01

, and

ζ = 770

. New positions in crystal fields of the

{}^{3}P

and

{}^{1}I

multiplets have been established, with centers of gravity being approximately 20 830

{cm}^{- 1}

for

{}^{3}P_{1}

, 21 470

{cm}^{- 1}

for

{}^{1}I_{6}

, and 22 640

{cm}^{- 1}

for

{}^{3}P_{2}
