Laser selective excitation, fluorescence line narrowing, and excited state absorption techniques have been used to investigate the electronic-energy-level structure of the 5 f[SUP7] ion Cm[SUP3+] in the host crystal LuPO[SUB4]. Crystal-field levels have been determined up to 35 700 cm[SUP-1] for the principal D[SUB2d] symmetry site. Eighty levels have been assigned and fitted to a parametric Hamiltonian with an rms deviation of 28.4 cm[SUP-1]. Inhomogeneous broadening of the electronic transitions and the small 9.5 cm[SUP-1] splitting of the nominally [SUP8]S[SUB7/2] ground multiplet are responsible for satellite lines reported previously. Time resolved fluorescence line narrowing was used to observe energy transfer between different subsites of the intrinsic Cm[SUP3+] center. It was found that electric-dipole interactions mediate this energy transfer. [ABSTRACT FROM AUTHOR] |
