N2 - Electron paramagnetic resonance (EPR) is applied to orthorhombic Rb1C60 1D polymer under hydrostatic pressure. The EPR linewidth is interpreted in terms of Elliott mechanism. EPR signal intensity provides us the antiferromagnetic transition temperature TN where the intensity drops suddenly. Finally, a phase diagram of the electronic states in o-Rb1C60 is constructed from TN vs pressure diagram, along with the resistivity under pressure, reported by Khazeni et al. [Phys. Rev. B 56, 6627 (1997)]. From this diagram we can definitely conclude that o-Rb1C60 is not a SDW system typical for 1D electronic band, but a 3D Mott-Hubbard insulator neara border of the transition.
