Abstract
Inelastic neutron-scattering measurements of acoustic magnons are reported for ferromagnetic Tb between 4.2 and 80 K for wave-vector transfers of 0.00 and 0.10 . Above 35 K we observe a double-peak structure in the scattered neutron intensity which is theoretically interpreted in terms of an interaction between the magnon and a magnetic exciton excited from an almost unpopulated state. This is the first observation of an interaction of this kind.
