利用光泵磁共振曲线测量氢原子密度(英文)

MEASUREMENT OF THE NUMBER DENSITY OF HYDROGEN ATOMS WITH THE PUMPING MAGNETIC RESONANCE CURVE

本文给出利用光泵磁共振曲线测量氢原子密度的实验.在我们的实验中,当射频源放电功率一定时,在25～61℃的泡温范围内测量到9.2×10^(11)～1.6×10^(11)(原子/厘米~3)的氢原子密度.实验结果表明,当放电功率一定时,氢原子密度随泡温升高而下降。

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.
