  Abstract. The gamma-ray multiplicity and total energy emitted by the heavy nucleus 254 No have been measured at 2 di erent beam energies. From these measurements, the initial distributions of spin I and excitation ...

(EDP Sciences, 2016)

  Superheavy nuclei exist solely due to quantum shell effects, which create a pocket in the potential-energy surface of the nucleus, thus providing a barrier against spontaneous fission. Determining the height of the ...

• Fission in the landscape of heaviest elements: Some recent examples 

  Khuyagbaatar, J.; Yakushev, A.; Düllmann, Ch.E.; Ackermann, D.; Andersson, L.-L.; Block, M.; Brand, H.; Even, J.; Forsberg, U.; Hartmann, W.; Herzberg, R.-D.; Heßberger, F.P.; Hoffmann, J.; Hübner, A.; Jäger, E.; Jeppsson, J.; Kindler, B.; Kratz, J.V.; Krier, J.; Kurz, N.; Lommel, B.; Maiti, M.; Minami, S.; Rudolph, D.; Runke, J.; Sarmiento, L.G.; Schädel, M.; Schausten, B.; Steiner, J.; De Heidenreich, T. Torres; Uusitalo, Juha; Wiehl, N.; Yakusheva, V. (EDP Sciences, 2016)

  The fission process still remains a main factor that determines the stability of the atomic nucleus of heaviest elements. Fission half-lives vary over a wide range, 10−19−1024 s. Present experimental techniques for ...

• Fission studies at IGISOL/JYFLTRAP: Simulations of the ion guide for neutron-induced fission and comparison with experimental data 

  Gao, Z.; Solders, A.; Al-Adili, A.; Canete, Laetitia; Eronen, Tommi; Jokinen, A.; Kankainen, Anu; Lantz, M.; Mattera, A.; Moore, Iain; Nesterenko, Dmitrii; Penttilä, Heikki; Pohjalainen, Ilkka; Rakopoulos, V.; Rinta-Antila, Sami; Vilén, Markus; Pomp, S. (EDP Sciences, 2020)

  For the production of exotic nuclei at the IGISOL facility, an ion guide for neutron-induced fission has been developed and tested in experiments. Fission fragments are produced inside the ion guide and collected using a ...

• Measurements of isomeric yield ratios of fission products from proton-induced fission on natU and 232Th via direct ion counting 

  Rakopoulos, Vasileios; Lantz, Mattias; Al-Adili, Ali; Gorelov, Dmitry; Jokinen, Ari; Kolhinen, Veli; Mattera, Andrea; Moore, Iain; Penttilä, Heikki; Prokofiev, Alexander V.; Solders, Andreas; Pomp, Stephan (EDP Sciences, 2017)

  Independent isomeric yield ratios (IYR) of 81Ge, 96Y, 97Y, 97Nb, 128Sn and 130Sn have been determined in the 25 MeV proton-induced fission of natU and 232Th. The measurements were performed at the Ion Guide Isotope Separator ...
