Popis: High-spin states in the N = 128 nucleus ²¹⁸Th have been investigated following fusion–evaporation reactions, using the recoil-decay tagging technique. Due to the short-lived nature of the ground state of ²¹⁸Th prompt γ rays have been correlated with the α decay of the daughter nucleus ²¹⁴Ra. The level scheme representing the decay of excited states has been extended to (16⁺) with the observation of six previously unreported transitions. The observations are compared with the results of shell model calculations and within the context of the systematics of neighbouring nuclei.
