N2 - We have measured the electrical resistivity under pressure up to 2 GPa for an antiferromagnet, CeRhGe. The resistivity at ambient pressure decreases monotonically below a Néel temperature TN = 10 K. With increasing pressure P, the resistivity has a peak around 10 K, which is anomalously enhanced up to 1.2 GPa. With further increasing pressure, the resistivity peak is diminished; the Néel temperature becomes zero at a critical pressure Pc = 1.9 GPa. The A-value of the resistivity ρ in the Fermi liquid relation ρ = ρ0 + AT2 is also found to increase with increasing pressure and has a maximum at Pc which corresponds to the value for the heavy-fermion superconductor CeCu 2Si2.
