<dt>Descripción</dt>
<dd>A magnetic plasmon (MP) is an acoustic mode of the degenerate electron gas which exhibits spin modulation but not charge modulation. It is driven by the exchange interaction. Its energy lies within the continuum of one particle excitations. Here we estimate the life-time of the MP and its cross section for the inelastic scattering of spin polarized neutrons. We conclude that its detection might be feasible in simple metals with large electron densities such as Aluminum.</dd>
