Above-barrier heavy-ion fusion cross-sections using the relativistic mean-field approach: case of spherical colliding nuclei

Maria V. Chushnyakova, Mrutunjaya Bhuyan, Igor I. Gontchar +1

The double folding (DF) approach is one of the widely used methods for finding nucleus-nucleus interaction potential. In the present work, the influence of the nuclear matter densi…

Testing the energy diffusion approximation for the escape of a Brownian particle from a potential pocket

Igor I. Gontchar, Maria V. Chushnyakova

For the first time, the energy diffusion approximation is confronted at the percent level with the exact numerical modeling of thermal decay of a metastable state. The latter is pe…

Probing the relativistic mean field effective NN forces for fusion of spherical colliding nuclei within a dynamical model

Maria Chushnyakova, Igor Gontchar, Natalya Khmyrova

For the first time, the precise data on the above barrier fusion (capture) cross-sections for the reactions involving spherical colliding nuclei are quantitatively analyzed using t…
