Decay of Uranium-235 After Neutron Capture

In atomic physics, different isotopes of the same element can exhibit significantly varied behaviors, particularly in nuclear reactions. Consider an isotope of uranium, Uranium-235, which is known for its role in nuclear fission. When U-235 captures a neutron, it can either release energy through fission or might remain stable. The process of neutron capture can also lead to the formation of an unstable isotope, which typically undergoes radioactive decay. If sufficient critical mass is achieved, a chain reaction can occur.

What is the primary type of decay that Uranium-235 might undergo after capturing a neutron and forming Uranium-236, which is an unstable isotope?
