High-precision experimental cross sections for the fusion of spherical nuclei are analyzed quantitatively using the effective interaction obtained with the relativistic mean field theory. Coulomb barriers are formed only for two of the four considere

Nucleon density is a fundamental quantity in nuclear physics. It is an important ingredient of the double folding model when calculating fusion cross sections of nuclei. A simplified way of calculating this density using the microscopic densities of

The time evolution of the thermally activated decay rates is considered. This evolution is of particular importance for the recent nanoscale experiments discussed in the literature, where the potential barrier is relatively low (or the temperature is

Nuclear fusion is an interesting example of collective nuclear motion; this process provides information on the interaction of nuclei and their structure. Theoretical analysis of fusion cross sections is often based on the double folding model, which

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. This model is useful in many branches of natural sciences: e.g. in biology, nuclear ph

The quasistationary decay rate of a metastable state, RD, often is interpreted as the inverse of the average lifetime of this state, τa. There are two ways for finding the rate: to evaluate it using one of the approximate Kramers formulas or to extr

Presently, it is well established that fission of excited nuclei is a dynamical process being a subject of fluctuations and dissipation. In the literature, there are indications that, at the compact nucleus shapes, the strength of nuclear friction is
