The temperature dependences of the critical field Hc2 (T) of an organic superconductor /?-(ET)2I3 with Tc =7.1 К is studied experimentally at temperatures 1.8-7.1 К and normal pressure in two orientations of the magnetic field,ТУ I\b' ζχιάΗ | |c*, in fields ranging from 0 to 140 kOe. The paramagnetic effect in this superconductor is found to be strongly suppressed. The reasons for this suppression are discussed.
