The contrasting fission potential-energy structure of actinides and mercury isotopes
Takatoshi Ichikawa, Akira Iwamoto, Peter Möller +1
Fission-fragment mass distributions are asymmetric in fission of typical actinide nuclei for nucleon number in the range and proton number in the…
Calculations of Branching Ratios for Radiative-Capture, One-Proton, and Two-Neutron Channels in the Fusion Reaction Bi+Zn
Takatoshi Ichikawa, Akira Iwamoto
We discuss the possibility of the non-one-neutron emission channels in the cold fusion reaction Zn + Bi to produce the element Z=113. For this purpose, we calculate…
Signature of smooth transition from diabatic to adiabatic states in heavy-ion fusion reactions at deep subbarrier energies
Takatoshi Ichikawa, Kouichi Hagino, Akira Iwamoto
We propose a novel extension of the standard coupled-channels framework for heavy-ion reactions in order to analyze fusion reactions at deep subbarrier incident energies. This exte…
Origin of the narrow, single peak in the fission-fragment mass distribution for Fm
Takatoshi Ichikawa, Akira Iwamoto, Peter Möller
We discuss the origin of the narrowness of the single peak at mass-symmetric division in the fragment mass-yield curve for spontaneous fission of Fm. For this purpose, we e…
Systematics of threshold incident energy for deep sub-barrier fusion hindrance
Takatoshi Ichikawa, Kouichi Hagino, Akira Iwamoto
We systematically evaluate the potential energy at the touching configuration for heavy-ion reactions using various potential models. We point out that the energy at the touching p…
Existence of One-Body Barrier Revealed in Deep Sub-Barrier Fusion
Takatoshi Ichikawa, Kouichi Hagino, Akira Iwamoto
Based on the adiabatic picture for heavy-ion reactions, in which the neck formation in the one-body system is taken into account, we propose a two-step model for fusion cross secti…
