Abstract: We give an experiment to measure the number density of hydrogen atoms by using the Pumping Magnetic Resonance Curve(PMRC). The number density from 9.2×1011 to 1.6×1011 (atoms/cm3) has been determined in the cell temperature region 25-61℃ and at a given r. f discharge power in our experiment. The number density of hydrogen atoms decreases as the cell temperature increases wtih a constant rf discharge power.

Key words: PMRC, Density of hydrogen atoms
