Abstract
The electron-paramagnetic-resonance spectrum of Pd3+ was studied in a single crystal of CaO at X-band frequency. The spectrum exhibits an intermediate quadrupole interaction and a static Jahn-Teller effect. The Jahn-Teller distortions produce the electric field gradient required for the quadrupole interaction. At high temperatures the spectrum is isotropic, and at low temperatures it consists of a superposition of three tetragonal spectra. It could be concluded that the first excited vibronic level is a singlet A1 and /35. The anomalous effects in the hyperfine structure, caused by the relatively large quadrupole interaction (Q/A0.59), were interpreted by an exact diagonalization of the spin Hamiltonian.
