Measurement of γ-ray Emission Probabilities for ¹⁰¹Mo

¹⁰¹Mo is one of the key nuclides in diagnosing fission burn-up. However, it’s difficult to measure its nuclear decay data due to its short half-life. Present study concerns in the measurements of γ-ray emission probabilities, P_γ, of ¹⁰¹Mo and ¹⁰¹Tc using the balance of scheme method and the entire process recording. The P_γ of ¹⁰¹Mo by the entire process recording is about 5% lower than that by using the balance of scheme method. The P_γ of 101Tc using the two methods agree each other very well. So, it seems the γ-ray emission probabilities as well as measurement method still need study further for ¹⁰¹Mo.
