✦ Synopsis
IN HONOR OF PROFESSOR GALEN STUCKY ON THE OCCASION OF HIS 65TH BIRTHDAY
Single crystals of yttrium aluminium borate, YAl 3 (BO 3 ) 4 , (referred to as YAB) doped with 20 and 40 mol% of Nd 3; were grown using a 6ux growth method. Inconsistencies in regard to the reported ground state splitting of the doped material are pointed out. A consistent splitting and assignment of the 4 I 9/2 ground state levels of the Kramers-ion Nd 3; was obtained by a combination of both, temperature-dependent 4 I 9/2 P 2 P 1/2 polarized absorption spectroscopy and room temperature 4 F 3/2 P 4 I 9/2 luminescence spectroscopy. The group theoretical implications of the crystal 5eld analysis are considered and discussed.
