Abstract : The recent observation of CESR in Palladium is described in detail. This is the first transition metal to be studied by this method, which allows also a determination of the electron-electron interaction responsible of the susceptibility enhancement. Indeed, this interaction gives rise to a resonance signal which is relatively narrow at low temperature < 100 gauss residual width and intense, and whose asymmetry is presently assigned to paramagnetic standing spin waves. Applying to the case of Palladium the classical analysis carried for simpler metals yields the g factor gPd = 2.25 ± 0.03 and the susceptibility enhancement factor mMATH-m 1 + Bo-1 ~ 16. However, a number of problems concerning the internal dynamics of electrons are left.
