The dhcp allotrope of Pr is a singlet ground-state system which is very close to magnetic ordering at low temperatures. We have observed quasi-elastic magnetic scattering around the q-value in the directions at which the disperion relations for the magnetic excitations have a minimum energy. The excitations were measured along all symmetry lines in the zone, and the dependence of the energies and lifetimes on the temperature and magnetic field was investigated.
