Proton Inelastic Scattering on Island-of-Inversion Nuclei
Abstract
The quadrupole collectivity of 28,30Ne and 32,34,36Mg, which are located around the conventional magic number of N = 20, was studied via proton inelastic scattering with a liquid hydrogen target by in-beam γ-ray spectroscopy in inverse kinematics. The deformation lengths were extracted from the angle-integrated cross sections for the first 2+ states using distorted-wave calculations. We have determined the deformation length of 36Mg to be 1.90 - 0.17 + 0.16 fm for the first time. For 34Mg and 30Ne, the accuracies were improved. The evolution of quadrupole deformation in the vicinity of 32Mg is discussed by comparing the present results with the theoretical calculations.
