摘要: 穆斯堡尔效应是一种无反冲的核γ射线的共振吸收现象,它是1958年由穆斯堡尔(R.L.M(?)ssbauer)发现的。由于穆斯堡尔效应产生的γ射线共振吸收谱线的能量宽度接近原子核能级的自然线宽,以及无反冲γ射线共振吸收(或散射)对γ射线能量变化十分灵敏,因此,可以把共振吸收的原子核当做灵敏的探针,测量固体中有关的原子核与核所在位置上固体的化学环境间的超精细相互作用。近些年来,穆斯堡尔效应已广泛应用于物理学、化学、生物学及矿物学的研究中来,穆斯堡尔谱仪已成为这些学科的重要研究工具之一。

Abstract: Seven samples of natural pyrope from different type rocks were analyzed by Mossbauer spectroscopy. The available spectra were fitted by computer to Lorentzian line shapes. It is found that the single peak area and intensity of the ferrous iron doublet are asymmetrical. And it is possible to distinguish the pyropes of kimberlite type from other type by asymmetrical parameters.
