Nuclear parameters determination of the 127Te β - decay: a proposal for teaching nuclear physics
Description
A study of the 127Te β- decay was carried out by means of gamma spectroscopy measurements using high resolution HPGe detector, in the region from 30 keV to 1.0 MeV, aiming to get a better understanding of the 127Te nuclear structure. The radioactive sources of 127Te were obtained from the 126Te(n,γ)1'27Te nuclear reaction produced in the IEA- R1 nuclear reactor at IPEN/CNEN-SP. Five gamma transitions previously attributed to this decay were confirmed with a better precision than previously. The half-life of 127Te was also studied resulting in data with lower uncertainty. Using a set of data selected from gamma spectroscopy measurements was developed and applied a didactic proposal for high school students using the Excel software. (author)
