Abstract

We report Hall-effect data (

R_{H}

) for two single crystals of the organic superconductor β-(BEDT-TTF

)_{2}

I_{3}

in the low-

T_{c}

phase (

β_{L}

). An unexpected temperature dependence is obtained with a broad maximum in

R_{H}

near 40 K. A possible interpretation in terms of electron-electron scattering is discussed.
