Due to the short-lived nature of the ground state of(218)Th prompt gamma rays have been correlated with the alpha decay of the daughter nucleus(214)Ra. 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. ; UK Science and Technology Facilities Council (STFC)Science & Technology Facilities Council (STFC); EU 7th Framework Programme 'Integrating Activities-Transnational Access'European Union (EU) [262010]; Academy of Finland under the Finnish Centre of Excellence Programme 2012-2017 (Nuclear and Accelerator Based Physics Programme at JYFL); Academy of FinlandAcademy of Finland [131665] ; Financial support for this work has been provided by the UK Science and Technology Facilities Council (STFC) and by the EU 7th Framework Programme 'Integrating Activities-Transnational Access', Project No.: 262010 (ENSAR) and by the Academy of Finland under the Finnish Centre of Excellence Programme 2012-2017 (Nuclear and Accelerator Based Physics Programme at JYFL).

8 pags., 10 figs., 2 tabs. ; The electron spectrometer, SPEDE, has been developed and will be employed in conjunction with the Miniball spectrometer at the HIE-ISOLDE facility, CERN. SPEDE allows for direct measurement of internal conversion electrons emitted in-flight, without employing magnetic fields to transport or momentum filter the electrons. Together with the Miniball spectrometer, it enables simultaneous observation of rays and conversion electrons in Coulomb excitation experiments using radioactive ion beams. ; The research leading to these results has received funding from the People Programme (Marie Curie Actions) of the European Union's Seventh Framework Programme (FP7/2007-2013) under REA grant agreement n 304033, by the Academy of Finland (contract number 265023) and by the United Kingdom Science and Technology Facilities Council (Grant Ref. ST/J000094/1). The Miniball collaboration is acknowledged for supporting this project. In addition, the German BMBF under contracts 05P15RDCIA and 05P15PKCIA and >Verbundprojekt 05P2015> are acknowledged. ; Peer Reviewed
