 /* Additional results shown but not compiled
    - The first observation of a new isotope 166Tb was carried out
      using its monoxide ions. Half-life of 166Tb is 21+-6 sec.
      Separation efficiency was reported.

 /* Experimental Method:
    - On-line mass separation (Gas-jet coupled thermal ion source was
      installed in the isotope separator on line.)
    - Gamma ray spectrometry
 /* By authors: Reaction yield was evaluated by the reaction cross
    section and correction made, if necessary for the charge
    distribution by assuming a Gaussian charge distribution with the
    most probable distribution Z(p) of the unchanged charge
    distribution model. */
