Indpeendent Yields of Iodine and Tellurium Isotopes in Fission of 232 Thorium with 30.5 MeV Alpha Particles

Iodine and tellurium isotopes produced in the fission of ²³²Th with 30.5 MeV alpha particles were separated using a method of sublimation in an air stream and the independent yields of ¹³⁰I, ¹³¹I, ^132m,gI, ¹³³I ¹³⁴I, ^134m,gTe, ^133mTe and ¹³⁴Te (cumulative) were determined by means of high resolution Ge(Li) γ-ray spectrometry. A Gaussian fit to the experimental data was used to obtain the width parameter σ_z and the most probable charge Z_p of the nuclear charge distribution in the isobaric chains 130 – 131. The most probable masses for fission fragments with Z = 52 and Z = 53 were also deduced from the measured fission yields.
