The isobaric analog state (IAS) of the halo nucleus 11Li has been investigated using the charge exchange reaction 11Li(p,n) 11Be* in inverse kinematics at E(11Li) = 64A MeV. The IAS was observed in 11Be, for the first time, at an excitation energy of 21.16 ± 0.02 MeV with a width of 0.49 ± 0.07 MeV (FWHM). The unit cross section, distortion factor and effective N-N interaction associated with the Fermi transition are extracted. Coulomb displacement energy, decay width, reaction variables and their relation to the halo structure are discussed.
