We report an Eliashberg analysis of the electron dynamics in
. The magnetic resonance at 41 meV
couples to charge carriers and defines the characteristic
shape in energy of the scattering rate
,
which allows us to construct the charge-spin spectral density
at temperature T. The T-dependence
of the weight under the resonance peak in
agrees
with experiment as does that
of the London penetration depth and of the microwave conductivity.
Also, the T=0 condensation energy,
the fractional oscillator strength in the condensate, and the ratio of
gap-to-critical temperature agree well with the data.
