摘要：

.The one-neutron halos lying in the island of inversion around N=20 has provided the podium to study the variation of total low-lying dipole strength with the neutron separation energy. We study three probable p -wave one-neutron halo candidates Ne-31 and Na-34 and Mg-37 lying in the island of inversion. A simple analytic model has been used for the calculation of the total low-lying dipole strength for the medium mass p -wave one-neutron halos. A correction factor to this analytical model has been estimated with a realistic Woods-Saxon potential. A comparison of these analytic calculations has been made with those performed by a finite-range distorted-wave Born approximation theory of the Coulomb dissociation. We also make an estimate of the one-neutron separation energies of Ne-31, Na-34 and Mg-37.
