← ScienceWhich outcome arises during radioactive decay into metastable isomers?
A)Gamma photon emission✓
B)Alpha particle ejection
C)Beta decay reduction
D)Neutron capture increase
💡 Explanation
Gamma photons are emitted because **isomeric transition** releases excitation energy; therefore, they stabilize an aroused isomeric nucleus rather than initiating particle emissions because those alterations do not adjust nucleon count significantly.
