The problem of finding the frequencies of small longitudinal oscillations of a spring having a finite mass and stiffness, attached at one end to a wall and at the other end to a body of finite mass, is discussed. This problem was repeatedly proposed

It is shown that the nontrivial energy dependencies of $D\bar{D}$, $D\bar{D}^{*}$, and $D^{*}\bar{D}^{*}$ pair production cross sections in $e^{+}e^{- }$ annihilation are well described within the approach based on account for the final-state interac

It is shown that an account for the final-state interaction of real or virtual nucleon and antinucleon produced in the processes $J/\psi\to p\bar{p}\gamma$, $\psi(2S)\to p\bar{p}\gamma$, $J/\psi\to p\bar{p}\omega$, and $J/\psi\to3\left(\pi^{+}\pi^{-}

We discuss the influence of various contributions of the $\Lambda_{c}\bar{\Lambda}_{c}$ potential on the energy dependence of the cross section $e^{+}e^{-}\rightarrow\Lambda_{c}\bar{\Lambda}_{c}$ near the threshold. New BESIII experimental data on th

The effect of screening by atomic electrons on the behavior of electron and positron wave functions in the continuous spectrum at small distances is studied. It is shown that these asymptotics are affected not only by the static potential of atomic e

The effects of final-state interaction of hadrons, produced in $e^{+}e^{-}$ annihilation near the threshold, are discussed. If there is a loosely bound state or a virtual state in a system of produced hadrons, then the energy dependence of hadroprodu

We show that the recent experimental data on the cross section of the process $e^{+}e^{-}\to\Lambda\bar{\Lambda}$ near the threshold can be perfectly explained by the final-state interaction of $\Lambda$ and $\bar{\Lambda}$. The enhancement of the cr

It is shown that the influence of the undulator field on the motion of a relativistic electron leads to a significant increase of the bremsstrahlung cross section on an atom near the end of the spectrum of undulator radiation. Observation of this eff

We consider the electron-positron pair production by a photon in Coulomb field near threshold. We obtain the analytical results for the particle energy spectrum and angular distribution exactly in the parameter $Ze^2/\hbar v$. We show that Furry-Somm
