We present simultaneously measured barrier distributions for the 20Ne + 208Pb system derived from largeangle quasielastic scattering and fusion, in the latter case by means of the detection of fission fragments. Both distributions turned out to be smooth, in spectacular disagreement with the results of standard coupled-channels calculations. Namely, they do not posses the strong structure expected from coupled-channels calculations, even if apparently they take into account explicitly all relevant strong couplings. This points to the importance of weak channels, i.e., transfer reactions and scattering connected with noncollective excitations.

Examination of the influence of transfer channels on the barrier height distribution: Scattering of 20Ne on 58Ni, 60Ni, and 61Ni at near-barrier energies

Trzcińska, A.; Piasecki, E.; Amar, A.; Czarnacki, W.; Keeley, N.; Kisieliński, M.; Kliczewski, S.; Kowalczyk, M.; Lommel, B.; Mutterer, M.; Siudak, R.; Stolarz, A.; Strojek, I.; Tyurin, Grigory; Trzaska, Wladyslaw (American Physical Society, 2016)

Background: It was suggested that the shape of the barrier height distribution can be determined not only by strong reaction channels (collective excitations) but also by weak channels such as transfers and/or ...
Mass distributions of the system 136Xe + 208Pb at lab energies around the Coulomb barrier: a candidate reactions for production neutron-rich nuclei at N=126

Kozulin, E.M.; Vardaci, E.; Knyazheva, Galina; Bogachev, Alexey; Dmitriev, S.N.; Itkis, Ioulia; Itkis, M.G.; Knyazev, A.G.; Loktev, T.A.; Novikov, K.V.; Razinkov, E.A.; Rudakov, O.V.; Smirnov, S.V.; Trzaska, Wladyslaw; Zagrebaev, V.I. (American Physical Society, 2012)

Reaction products from the system 136Xe+208Pb at 136Xe ions laboratory energies of 700, 870, and 1020 MeV were studied by two-body kinematics and by a catcher-foil activity analysis to explore the theoretically proposed ...
Transfer cross sections at near-barrier energy for the 24Mg + 90,92Zr systems

Wójcik, D.; Trzcinska, A.; Piasecki, E.; Kisielinski, M.; Kowalczyk, M.; Wolinska-Cichocka, M.; Bordeanu, C.; Gnoffo, B.; Jia, H.; Lin, C.; Martorana, N.S.; Mutterer, M.; Pagano, E.V.; Piasecki, K.; Russotto, P.; Quatrocchi, L.; Trzaska, Wladyslaw; Tiurin, G.; Wolski, R.; Zhang, H. (Jagellonian University, 2018)

We have tested the hypothesis that for systems 24Mg + 90,92Zr, the shape of the barrier height distribution is not influenced by transfers processes. The experiment was performed using the ICARE detector system at the ...
Gamma rays as probe of fission and quasi-fission dynamics in the reaction 32S + 197Au near the Coulomb barrier

Pulcini, A.; Vardaci, E.; Kozulin, E.; Ashaduzzaman, M.; Borcea, C.; Bracco, A.; Brambilla, S.; Calinescu, S.; Camera, F.; Ciemala, M.; Canditiis, B. de; Dorvaux, O.; Harca, I.

Compound nucleus fission and quasi-fission are both binary decay channels whose common properties make the experimental separation between them difficult. A way to achieve this separation could be to probe the angular ...

V.; Singh, Pushpendra P.; Sahoo, Rudra, N.; Gall, B.; Asfari, Z.; Borcea, C.; Harca, I.; Filipescu, D. M. (American Physical Society (APS), 2020)

Background: The formation of superheavy nuclei in fusion reactions is suppressed by a competing quasifission process. The competition between the formation of the compound nucleus and the quasifission depends strongly on ...
