Description

Elastic magnetic electron-scattering form factors from 29Si and 31P have been measured in the range of momentum transfer from 1.0 to 2.8 fm-1. Analysis of the data using a particle-core-coupling model yields 2ssub(1/2) occupation probabilities for the valence nculeon of 0.46 +- 0.01 for the neutron in 29Si and 0.48 +- 0.01 for the proton in 31P. The radius of the 2ssub(1/2) proton orbit in 31P has been found to be (5.3 (+2.6 -1.5))% larger than the corresponding neutron orbit in 29Si. Recent large-basis shell-model calculations of the form factors do not accurately reproduce the experimental results. (orig.)
