分子式：
CAS号：
性质：将含钾样品放入核反应堆中接受快中子照射，40K核被打进一个中子，而后放出一个质子，形成39Ar，用质谱计测定被照射样品的40Ar/39Ar比值，代替常规钾-氩法中40Ar/40K比值，从而计算出样品年龄的方法，计算公式如下：t=λ-1ln(1+J•40Ar/39Ar)。式中J=39Ar/40Ar•λ/λkΔT∫φ(ε)σ(ε)dε是样品照射持续的时间，Ф(ε)是能量为ε时的中子通量，σ(ε)为39K(n，p)39Ar的反应截面，实验中用一已知年龄(ts)的标准与待测样品一块进行辐照，由下式求得J值：J=(eλt-1)/(40Ar/39Ar)。此方法解决了过去钾、氩分别由不同方法测定所产生的不同误差使年龄精度较低的弊端；同时由于照射后样品氩的释放可采用阶段加温方法，对一个样品便可获得一系列的表面年龄，最终得到代表矿物或岩石结晶的稳定坪年龄；或由等时线法处理得到样品的年龄、认识外来氩的混入状况。
