Recent data on transition strengths, namely the hitherto unknown B(E2) values of radioactive Nd-140 and Sm-142 in the N=80 isotones, have suggested that the proton 1g7/2 subshell closure at Z=58 has an impact on the properties of low-lying collective states [1,2].
The unstable, neutron-rich nuclei Nd-140 and Sm-142 were investigated via projectile Coulomb excitation at the REX-ISOLDE facility...

Level densities are fundamental quantities in the description of many-body systems. Besides their importance as a basic nuclear structure property, it is well known that, through the statistical model of nuclear reactions, level densities have a strong impact on the results of calculations of other nuclear physics observables. This is particularly so for thermonuclear rates in nucleosynthesis...

In our previous pablications devoted to the collinear cluster tri-parttition of the low excited nuclei [1, 2] we have discussed the role of scattering medium in the registration of the CCT products. Briefly, even if initially two CCT partners fly in the same direction perfectly collinearly they get some angular divergence after passing the scattering medium on the flight pass due to the...

The results of measuring the radii of some excited states of light nuclei are presented. A method based on the analysis the diffraction patterns of the cross-section (Modified diffraction model MDM) was proposed. We studied the inelastic α-scattering on 9Be, 11B, 12C and 13C with the excitation of some excited states whose structure recently attracted a lot of attention from different...

The effect of the electron screening on the alpha decay rate of typical nuclei is considered. To this end, the adiabatical approach is exploited, which consecutively takes into account the adiabaticity of the motion of the alpha particle through the shells [1]. The effect is found to be of the order of one tenth to one hundredth of a percent for the considered representative nuclei. The method...
