In: Chemical Physics Letters Nr. 6, Jg. 215(1993), S. 668-673.http://hdl.handle.net/2003/2534210.17877/DE290R-2763The decay rates of the nuclear spin polarization of Pr^(3+) in a YAlO_3 matrix were measured in the temperature range 3-9 K by time-resolved spectral hole burning and simultaneous radio-frequency irradiation. In the low-temperature limit, diffusion of spin polarization to other regions of the inhomogeneously broadened optical line dominates the relaxation. At higher temperature, thermally activated multiple phonon processes become dominant.enElsevier53010.1016/0009-2614(93)89375-Rarticle (journal)
