/* 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. */
