摘要
在高对比度透射光谱中观察到线宽18mG(FWHM)钠原子基态中碰撞增强的Hanle共振.此共振的线宽仍表现出Dicke变窄效应,但信号的强度却随着缓冲气体压强急剧地增加.
Collision-enhanced Hanle resonances in the ground state of Na atoms with a linewidth of 1 8mG(FWHM) have been observed in the high-contrast transmission spectroscopy. The width of theseiresonances still shows Dicke narrowing effect, but the signal intensity drastically increases with increasing the buffer gas pressure.
