Based on the theoretical description of chiral symmetry in nuclear system by Fauendorf and Meng, some chiral doublet bands were suggested in different mass regions. It was revealed at iThemba LABS that Tl isotopes form a new region
where chirality could develop. In particular 194Tl was found to be perhaps the best chiral candidate up to date. 193Tl as a neighbour of 194Tl is thus likely to be a very good chiral candidate. In order to search for possible chiral doublet bands in 193Tl, an experiment was performed using the 160Gd(37Cl,4n) reaction. The analysis showed that two aside bands could be chiral partners to Band 2. However, statistics were not enough to determine the linking transitions and their
spin and parity assignments. Thus, another experiment was performed using the reaction of 181Ta(18O,6n) which has much larger cross-section for production of 193Tl. The faster digital electronics was also employed. Alternatively:
The new data set has much larger statistics. Analysis for these new data is in progress. The results obtained so far will be presented.
