Anomalous electron-electron scattering contribution to the electrical resistivity of lithium

The electron-electron scattering contribution to the electrical resistivity of Li has been measured. The coefficient of the T2 term was found to be 3.0+or-0.1 p Omega cm K-2, which is more than an order of magnitude larger than the value for Na and K. The anomalously large value for Li is attributed to the anisotropy of the electron relaxation time.
