A study of α-decay for ^192,194Po and ^188,190Pb was performed in the reaction of ³⁶Ar on ¹⁶⁰Dy at 176 MeV, The formation cross section was obtained to be 5.0±0.2 µb for ¹⁹²Po and 11.6±0.3μb for ¹⁹⁴Po. The resulting reduced α width δ² was 38(5) keV for ¹⁸⁸Pb and 25(3) keV for ¹⁹⁰Pb, which further confirmed the magic characteristics for neutron-deficient nuclei of Z=82.
