/* Experimental Method:
- Stacked target irradiation (Energy of incident alpha particles
at each stacked foil was estimated from the range-energy relation
given by Bichsel et al. [H. Bichsel et al., Phys. Rev.
105(1957)1788].)
- Activation (Activation were performed for the order of 1000
micro-Curie in 5 to 30 min for the short-lived activities and
5000 micro-Curie in 4 to 5 h for the long-lived ones.)
- Chemical separation (Efficiencies of chemical separations are
tabulated in Table I, p277 in the reference)
