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

Introduction

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
