Abstract
The nuclei 220,222Rn have been studied, using the alpha -radioactive sources 226Ra and 228Th, via the technique of alpha - gamma angular correlation. This has enabled Jpi assignments to be made to the previously known low-lying levels in 220,222Rn and alpha hindrance factors to be interpreted. The systematics of alpha hindrance factors for these Z=86 nuclei are examined and compared with those of Z=88, 90 nuclei. The subsequent alpha decays to 216,218Po were observed and 2+ assignments confirmed for the first excited states in these nuclei.Keywords
