States in the {sup 11}Be spectrum, termed halo analog (HA) states, with halo isospin {ital T}{sup {ital h}}=1, 0 are studied in the framework of a three-body ({sup 9}Li+{ital n}+{ital p}) approach and a microscopic hyperspherical harmonics method. Three-body bound and scattering (HA) states, with structure similar to the two-neutron halo state of {sup 11}Li, are obtained in {sup 11}Be at the excitation energies above 18 MeV and compared with experimental spectra. The influence of the ``deuteronlike`` halo analog state with {ital T}=3/2 ({ital T}{sup {ital h}}=0) on {beta}-delayed deuteron emission from {sup 11}Li is studied. It is found that the shape of the deuteron spectrum and branching ratio to the {sup 9}Li+{ital d} channel are sensitive to the position of this halo analog state in {sup 11}Be.
