Macroscopic model of magnetic dipole resonance in spherical nuclei
Bastrukov S. I. , Molodtsova I. V.
A macroscopic mechanism for nuclear magnetization associated with a magnetic dipole resonance is analyzed. The giant Ml resonance is shown to be a consequence of oscillations excited in the magnetization current in a peripheral layer of finite depth. The collective model discussed here gives a satisfactory description of the empirical behavior of the energy position of the peak as a function of the mass number: E(M 1) = 40.&4 ~1/3 Mev. The model predicts that the resultant branching ratio will depend on the atomic number and mass number in accordance with β(ΛΠ) = 8.5Χ 1(Γ2Ζ2Α-2/3/4· © 1995 American Institute of Physics.
