A new ESR signal has been observed in y-irradiated Y-type zeolite, the Naf ions of which have been exchanged by divalent cations such as Mgzf or Ca\*+. Its ESR parameters are as follows: gt = 2.0065,ga = 2.0060 andgs = 2.0021 k 0.0002 and Ct = 41. C2 = 42.5 and C3 = 73 + 0.5 Oe for hlgY samples andg
