Inelastic and elastic neutron scattering data on Pb{sub 2}Sr{sub 2}PrCu{sub 3}O{sub 8+{delta}} are presented. Magnetic ordering of the Pr moments is found to be analogous to the Tb analogue, interpreted with two different wave vectors k = 0 0 0 and 0 0 1/2. A molecular field-induced shift is observed in the low-energy inelastic neutron scattering (INS) data when going through the Neel temperature. This shift is quantitatively accounted for by the magnetic order of the Pr sublattice. The crystalline-electric-field (CEF) potential has been determined from the observed magnetic excitations and is compared with those of Pr in other cuprates. These results underline the relevance of the quasi-triplet ground state splitting for T{sub c} suppression by Pr in the cuprate superconductors.
