The deformations in 20Ne, 24Mg and 28Si from electron scattering

Abstract The data of elastic and inelastic electron scattering from 0+, 2+, 4+ states in 20Ne, 24Mg and 28Si were analyzed within a framework of the rotational model. The fits to the data are achieved by extending the Nilsson orbits to include higher oscillator states and introducing an additional Y4 deformation into the Nilsson field.

Radial Distribution of Valence Neutrons from Elastic Electron Scattering

Cross sections for elastic scattering of 175--300-MeV electrons by the nuclear magnetization current density of /sup 87/Sr have been measured. The results are used to determine the shape of the radial wave function of the valence neutron shell. The experiment yields a rms radius of 1g/sub 9///sub 2/ neutrons that is 0.31 +- 0.04 fm smaller than predicted by density-dependent Hartree-Fock theory.

On the radial distribution of the 1f72 proton orbit

Abstract Cross sections for magnetic elastic electron scattering of high multipolarity from 51 V and 59 Co have been measured. They are interpreted in terms of the rms radius of the 1f 7 2 proton orbit. The results for 51 V and 59 Co 1f 7 2 rms radii are smaller by 3% and 9%, respectively, than predicted by the Hartree-Fock-Bogoliubov theory.

Elastic electron scattering from the magnetization distribution of 4193Nb

Abstract Cross sections of elastic magnetic electron scattering from 41 93 Nb have been obtained at momentum transfers from 1.7 to 2.5 fm −1 . The observed deviation of the dominant M9 amplitude from the 1 g 9 2 single-proton value can be explained by large-space shell model calculations.
