    "abstract": "Enhanced positron annihilation on polyatomic molecules is a long-standing and\ncomplex problem. We report the results of calculations of resonant positron\nannihilation on methyl halides. A free parameter of our theory is the positron\nbinding energy. A comparison with energy-resolved annihilation rates measured\nfor CH$_3$F, CH$_3$Cl, CH$_3$Br [Barnes et al. Phys. Rev. A {\\bf 74}, 012706\n(2006)] shows good agreement and yields estimates of the binding energies.",
