Barrier Distributions as a Tool to Investigate Fusion and Fission
M. Dasgupta, D. J. Hinde, J. R. Leigh +1
The recent availability of precisely measured fusion cross-sections has enabled the extraction of a representation of the distribution of barriers encountered during fusion. These…
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…
Importance of Non-Linear Couplings in Fusion Barrier Distributions and Mean Angular Momenta
K. Hagino, N. Takigawa, M. Dasgupta +2
The effects of higher order coupling of surface vibrations to the relative motion on heavy-ion fusion reactions at near-barrier energies are investigated. The coupled channels equa…
Adiabatic quantum tunneling in heavy-ion sub-barrier fusion
K. Hagino, N. Takigawa, M. Dasgupta +2
High precision measurements of the fusion excitation functions for the reactions ^{40}Ca + ^{194}Pt, ^{192}Os clearly demonstrate that projectile excitation significantly modifies…
Validity of the linear coupling approximation in heavy-ion fusion reactions at sub barrier energies
K. Hagino, N. Takigawa, M. Dasgupta +2
The role of higher order coupling of surface vibrations to the relative motion in heavy-ion fusion reactions at near-barrier energies is investigated. The coupled channels equation…
