Journal ArticleDOI
Barrier distributions from the fusion of oxygen ions with Sm 1 4 4 , 1 4 8 , 1 5 4 and W 186
J.R. Leigh,Mahananda Dasgupta,David Hinde,J. C. Mein,Clyde Morton,R. C. Lemmon,John Lestone,John Newton,Heiko Timmers,J. X. Wei,N. Rowley,N. Rowley +11 more
TL;DR: In this representation it is clearly seen that the excitation functions are not smooth and featureless; each is unique and is shown to depend on the details of the structure of the interacting nuclei.
Journal ArticleDOI
Conclusive evidence for the influence of nuclear orientation on quasifission.
TL;DR: Fission fragment anisotropies and mass distributions have been measured to high accuracy, over a wide range of angles, for the full momentum transfer fission reaction as mentioned in this paper, where the bombarding energies spanned the fusion barrier distribution, in steps of 1 MeV.
Journal ArticleDOI
A case study of collectivity, transfer and fusion enhancement
Heiko Timmers,Dieter Ackermann,S. Beghini,L. Corradi,J.H. He,G. Montagnoli,Fernando Scarlassara,A. M. Stefanini,Neil Rowley +8 more
TL;DR: In this paper, precise fusion and quasi-elastic scattering excitation functions have been measured for the systems 40 Ca + 90,96 Zr at energies spanning the Coulomb barrier.
Journal ArticleDOI
Fusion-Fission versus Quasifission: Effect of Nuclear Orientation
David Hinde,Mahananda Dasgupta,J.R. Leigh,John Lestone,J. C. Mein,Clyde Morton,John Newton,Heiko Timmers +7 more
TL;DR: Fission fragment angular distributions and cross sections have been measured for the reaction of [sup 16]O+[sup 238]U at energies around the Coulomb barrier, interpreted as showing that collisions with the tips of the deformed target nucleus lead to quasifission, collision with the sides to fusion-fission.
Journal ArticleDOI
Experimental barrier distributions for the fusion of 12 C, 16 O, 28 Si and 35 Cl with 92 Zr and coupled-channels analyses
John Newton,Clyde Morton,Mahananda Dasgupta,J.R. Leigh,J. C. Mein,David Hinde,Heiko Timmers,Kouichi Hagino +7 more
TL;DR: In this paper, the authors measured the excitation functions for the fusion of the Coulomb barrier regions and compared with the results of realistic coupled-channels calculations, which included couplings to all orders and treated excitation energies correctly.
