Surface diffuseness anomaly in heavy-ion fusion potentials
K. Hagino, M. Dasgupta, I. I. Gontchar +3
Recent high precision experimental data for heavy-ion fusion cross sections at energies in the vicinity of the Coulomb barrier systematically show that a strikingly large surface d…
Influence of higher-order deformations in the ^{34}S + ^{168}Er fusion reaction
C. R. Morton, A. C. Berriman, R. D. Butt +5
The shape of the measured barrier distribution for the ^{34}S + ^{168}Er reaction is analysed using the coupled-channels description. The ^{168}Er nucleus is a good candidate to te…
Coupled-channels analysis of the O+Pb fusion barrier distribution
C. R. Morton, A. C. Berriman, M. Dasgupta +4
Analyses using simplified coupled-channels models have been unable to describe the shape of the previously measured fusion barrier distribution for the doubly magic O+$^{208…
Fusion versus Breakup: Observation of Large Fusion Suppression for ^9Be + ^{208}Pb
M. Dasgupta, D. J. Hinde, R. D. Butt +8
Complete fusion excitation functions for Be + Pb have been measured to high precision at near barrier energies. The experimental fusion barrier distribution extracted…
Quasi-fission reactions as a probe of nuclear viscosity
J. Velkovska, C. R. Morton, R. L. McGrath +2
Fission fragment mass and angular distributions were measured from the ^{64}Ni+^{197}Au reaction at 418 MeV and 383 MeV incident energy. A detailed data analysis was performed, usi…
Evidence of Double Phonon Excitations in ^{16}O + ^{208}Pb Reaction
M. Dasgupta, K. Hagino, C. R. Morton +5
The fusion cross-sections for ^{16}O + ^{208}Pb, measured to high precision, enable the extraction of the distribution of fusion barriers. This shows a structure markedly different…
