Two-center level diagrams for the neutron orbitals in the scattering of '60 on "Mg and of "0 on 24Mg are calculated by using a deformed potential for 24,25Mg. Possible consequences of the nuclear Landau-Zener mechanism, namely the promotion of nucleons at avoided level crossings, and of the rotational coupling between crossing molecular singleparticle orbitals are studied for inelastic excitati...

Cold neutrons are converted to ultra-cold neutrons (UCN) by the excitation of a single phonon or multiphonons in superfluid helium. The dynamic scattering function S(q, ω) of the superfluid helium strongly depends on pressure, leading to a pressuredependent differential UCN production rate. A phenomenological expression for the multiphonon part of the scattering function s(λ) describing UCN pro...

The nuclear effects in the spin-dependent structure functions g D 1 and b D 2 are calculated in the relativistic approach based on the Bethe-Salpeter equation with a realistic meson-exchange potential. The results of calculations are compared with the non-relativistic calculations. The problem of extraction of the neutron spin structure function, g n 1 , from the deuteron data is discussed. In ...
