Guided by the sudden drop in Hall coefficient below 20 K in beta-(BEDT
TTF)2I3 we have searched for further evidence of phase transition at 2
0 K by both transport and thermodynamic measurements. We observe anoma
ly in both temperature dependence of resistance and in specific heat n
ear 22 K. We compare our results with other measurement on beta-(BEDT-
TTF)213 in this temperature range. We also discuss the relation of thi
s transition at 20 K to the two superconducting states with T(c)'s e.g
. 1.5 K and 8 K.
