 /* Experimental Method:
    - Stacked target irradiation (A stack of 21 targets set in a
      multiple-target chamber with 5 mm spacing)
    - Collection by He jet (Products attached to the PbI2 aerosol
      clusters were swept out of the target chamber)
    - On-line mass separation (JAERI-ISOL. Mass resolution of A/Delta
      A is about 850 at the mass number A=208 [S. Ichikawa et al.,
      Nucl. Instrum. Methods B187(2002)548].)

    - Decay curve analysis
