Abstract / Description:We present secure [N II]205 μm detections in two millimeter-bright, strongly lensed objects at high redshift, APM 08279+5255 (z = 3.911) and MM 18423+5938 (z = 3.930), using the IRAM Plateau de Bure Interferometer. Due to its ionization energy [N II]205 μm is a good tracer of the ionized gas phase in the interstellar medium. The measured fluxes are S([N II]205 μm) = (4.8 ± 0.8) Jy km s-1 and (7.4 ± 0.5) Jy km s-1, respectively, yielding line luminosities of L([N II]205 μm) = (1.8 ± 0.3) × 109 μ-1 L &sun; for APM 08279+5255 and L([N II]205 μm) = (2.8 ± 0.2) × 109 μ-1 L &sun; for
