Sub-barrier heavy-ion fusion/capture: Accurate accounting for zero-point quadrupole shape oscillations with realistic nucleus-nucleus potential
I. I. Gontchar, M. V. Chushnyakova
Although the study of collisions of heavy ions resulting in formation of dinuclear systems has a long history this process still is a subject of experimental and scientific activit…
Systematic application of the M3Y NN forces for describing the capture process in heavy-ion collisions involving deformed target nuclei
I. I. Gontchar, M. V. Chushnyakova, O. M. Sukhareva
We present results of a systematic study of the capture process through the barrier penetration model. The nucleus-nucleus interaction potential is calculated using the double-fold…
Accuracy of the analytical escape rate for a cusp barrier in the overdamping regime
Alexander Zakharov, Maria Chushnyakova, Igor Gontchar
For the first time, the accuracy of the approximate analytical Kramers formula for the thermal decay rate over a cusp barrier, , is checked numerically for the overdamping reg…
Two ways for numerical solution of the Kramers problem for spatial diffusion over an edge-shaped barrier
Maria Chushnyakova, Igor Gontchar, Alexander Zakharov +1
Thermal decay rate over an edge-shaped barrier at high dissipation is studied numerically through the computer modeling. Two sorts of the stochastic Langevin type equations are app…
