Abstract

A new method, based on the excitation of the anti-analog giant dipole resonance (AGDR) in (p; n) reaction, for measuring the neutron-skin thickness has been tested. The γ γ-decay of the AGDR to the isobaric analog state (IAS) has been measured. The difference in excitation energy of the AGDR and IAS was calculated. By comparing the theoretical results with the measured one, the Rpn value for 124Sn was deduced to be 0:209 ± 0:066 fm. The present method provides a new possibility for measuring neutron-skin thickness of very exotic nuclei.
