1 and 239 (239 is a prime number).

239 is a Prime Number.
239 is an odd number
When a fast-moving neutron hits a nonfissionable uranium-238 (U-238) nucleus and is absorbed, an atom of fissionable plutonium-239 (Pu-239) is produced.
For decays by alpha emission use the general formula: A/Z X --> 4/2 He + A-4/Z-2 Y *Where A is atomic mass and Z is atomic number. So for U-238 238/92 U --> 4/2 He + 234/90 Th
When a fast-moving neutron hits a nonfissionable uranium-238 (U-238) nucleus and is absorbed, an atom of fissionable plutonium-239 (Pu-239) is produced.
Plutonim is obtained from uranium by nuclear reactions: U 238 + 1 neutron → U 239 → Np 239→ Pu 239
92U-238 + 0n ------92U-239----- β ----- 93Np-239------ β --------94Pu-239
