Production of Carrier-Free ¹³²Cs and ¹²⁹Cs

Carrier-free ¹³²Cs and ¹²⁹Cs were produced by the ¹²⁹I(α,n)¹³²Cs, ¹²⁹I(α,4n)¹²⁹Cs, and ¹²⁷I(α,2n)¹²⁹Cs reactions using thallous iodide as a recoverable target. Upper limits for the production yields of these isotopes are ²⁵µC/(µA h) for ¹³²Cs and 2 mC/(µA h) for ¹²⁹Cs, for 35-MeV alpha particles.
