The Role of Fission in the Search of the Super Heavy Land: Fission Modes in Heavy and Superheavy Nuclei. Case Study of *1*8*0Hg / E.Vardaci, N.Carjan, E.M.Kozulin, I.M.Itkis, G.N.Knyazheva, D.Kumar, K.V.Novikov, I.V.Vorobiev, M.Cheralu, N.I.Kozulina, I.V.Pchelintsev, [a.o.] // HINPw7 – 7th International Workshop of the Hellenic Institute of Nuclear Physics on Nuclear Structure, Astrophysics and Reaction Dynamics, University of Ioannina, Greece, May 31-June 1, 2024 [Electronic resource] / Ed.: A.Pakou, G.Souliotis, C.Moustakidis. – Les Ulis Cedex : EDP Sciences, 2024. – P. 01003. – URL: https://doi.org/10.1051/epjconf/202430401003. – Bibliogr.: 35.
Many observations strongly support the hypothesis that nuclei may fission through several independent fission modes (multimodal fission) interpreted as different prescission shapes and fission paths in a multidimensional potential energy landscape where shell effects are dominant. Mass distributions of the fission fragments are sensitive to the potential energy landscape and appear to be single humped (symmetric) or double humped (asymmetric). In many cases a mixture of both modes is observed. We propose here our study on 180Hg. Binary fission fragments formed in the reaction 68Zn + 112Sn → 180Hg at different excitation energies around the Coulomb barrier were detected using the double-arm time-of-flight technique with the spectrometers CORSET. The experiment was performed at JYFL (Jyvaskyla, Finland). We will discuss an analysis of the mass distributions in terms of fission modes predicted by a five-dimensional fission model. We have found out that the mass distributions can be well reproduced by considering a symmetric fission mode and two asymmetric modes at (AL ≈ 80, AH ≈ 100) and (AL ≈ 70 and AH ≈ 110). – (EPJ Web of Conferences ; Vol. 304) .
