Fine structure in the α decay of ²¹⁸At

RADIOACTIVITY ²¹⁸At(α)[from U(p, F), E=1.4 GeV, followed by selective ionization of ²¹⁸At using RILIS at CERN-ISOLDE facility]; measured Eα, Iα, Eγ, Iγ, αγ-coin, half-life of ²¹⁸At decay using silicon detectors for α detection and low-energy Ge detector for γ detection. ²¹⁴Bi; deduced levels, J, π, α feedings, α hindrance factors. ²¹⁸At; deduced J, π. Systematics of low-lying level energies in ^210,212,214Bi, ^212,214,216At, and α hindrance factors in the decays of ^214,216,218At, ²¹⁶Fr. Comparison with theoretical predictions, and with previous experimental results.
