Alternating parity bands in doubly odd 218Ac129 and octupole instability in the light actinide region

High-spin states of doubly odd 218Ac1129 have been investigated using in-beam α, γ and conversion electron spectroscopy techniques through the 209Bi(12(13)C,3(4)n) fusion-evaporation reactions. The level scheme of 218Ac shows three interconnected, alternating parity structures, each one linked by st...
