The reaction of Pu-239 with which particles produces a neutron and Cm-242?rnPositronrnGammarnBetarnAlpha

Accepted Answer

The correct answer is alpha.
The reaction is:
²³⁹Pu + α → ²⁴²Cm + ¹n
This is an example of alpha decay where a plutonium-239 nucleus absorbs an alpha particle (which is essentially a helium nucleus, ⁴He), resulting in the formation of curium-242 and a neutron.
