Abstract
The role of surface neutrons in nuclear properties was examined by comparing rigidities of nuclear collective vibrations and charge radii of even-even nuclei. Correlations of peaks in rigidities and minimal values of r 0 = Rch · A −1/3 parameters were revealed.
Highlights
Eighty years of nuclear investigations have revealed a large variety in nuclear characteristics, their consistent theoretical interpretation is up to now only partly successful
The theory of multipole giant resonances (MGR) observed experimentally in the cross sections of different reactions on even-even nuclei cannot explain in full extent a great variety of their forms and widths
The rigidity Cλ which determines the potential energy of nuclear deformation is connected with the nuclear surface tension
Summary
Eighty years of nuclear investigations have revealed a large variety in nuclear characteristics, their consistent theoretical interpretation is up to now only partly successful. For the quadrupole surface vibrations (λ = 2) the connection of rigidity with the surface tension σ of a nucleus having the charge and radius Ze and R, respectively, has the form Nuclear rigidity as regards to quadrupole vibrations is connected with the energy of the first collective 2+1 state and the mean squared deformation of a nucleus β
