[en] Using gaseous sources of I₂ and HI containing the radioactive isotopes ¹²⁴I and ¹²⁶I effective cross sections for nuclear resonance scattering from the first 2⁺ states of ¹²⁴Te and ¹²⁶Te were measured. Information is obtained about the charging of the nonradioactive molecular partner after EC decay, the interaction of highly charged ions with neutral molecules, and the slowing down of atoms in a Xe buffer gas. Indications of an iodine complex being stable in the gaseous phase are found. (orig.)

[en] In this work, the half life of the beta-unstable nucleus ¹²⁷Te was studied using neutron-irradiated samples of ¹²⁶Te. The gamma activity of each of the irradiated samples was followed for 3-5 consecutive half lives. The results were analysed in two different ways, and the resulting half-life was 9.295(5)h, which is compatible with the tabulated value of 9.35(7)h, with much lower uncertainty.

[en] The half-lives of the 1776.8 keV 6⁺ level and the 2497.3 keV 7^- level in ¹²⁶Te are measured by registering β-γ coincidences in the decay of ¹²⁶Sb. The results are Tsub(1/2)(1776.8) = 66+-3 ps and Tsub(1/2)(2497.3) = 152+-5 ps. The collective strength of the 6⁺→4⁺ transition depopulating the 1776.8keV state is estimated. An additional half-life of 0.36+-0.06 ns is found but not definitely assigned in the level scheme. (Auth.)

[en] Angular distribution data for the mutual excitation of the ¹²⁶Te and ²²Ne 2⁺ states have been measured for the inelastic scattering of 93.5 MeV ²²Ne on ¹²⁶Te. Data for transitions to the ground states, the ¹²⁶Te 2⁺ state and the ²²Ne 2⁺ state were also obtained. A coupled-channels analysis of the reaction is found to provide a good description of the general features of the data. (Auth.)

[en] Many nuclei in the mass region ∼ 130 e.g. ¹³⁸Gd, ¹³⁶Sm, ¹³⁴Nd, ¹³²Ce, ¹³⁰Ba, ¹²⁸Xe have been found in the literature to have K-isomers. The nucleus ¹²⁶Te has been chosen for studying K-isomerism. This nucleus is expected to have γ - soft behavior and may exhibit K-isomerism as predicted by Xu et al. The energy states up to 10 h have been identified in ¹²⁶Te. The plan was to build the level scheme first and then look for the isomer, if there is any. Here the experimental result on the excited states of ¹²⁶Te have been presented

[en] The analysis of experimental data on some nuclei where the resonance level was decayed by excitation of quasi rotational band was done. For these nuclei the relation of forces of dipole transitions was determined. (A.A.D.)

[en] A search for isomeric states was performed in the nucleus 60140Nd80 using in-beam γ-ray spectroscopy and the 126Te(18O,4n) reaction. Prompt and delayed γ-ray coincidences were measured with the AFRODITE spectrometer using the pulsed beam delivered by the Separated Sector Cyclotron of iThemba LABS. One new isomer was identified, with spin-parity Iπ=20+ and lifetime T1/2≥400 ns, at an excitation energy Ex=7430 keV. The lifetime of the 10+ isomer at Ex=3619 keV was determined to be 32.9(1.8) ns, confirming the previously reported value. The configuration of the Iπ=20+ isomer is assigned based on configuration-dependent cranked Nilsson-Strutinsky (CNS) calculations as a state π(d5/2g7/2)10+-4xν(h11/2-2)10+, with the spin vectors of the six holes in the 64146Gd82 core fully aligned
