• The excited state theruaaodynan'nic Betlue ansatz (TBA) eqtmations for the spir?Iess Feruniozazauodel are presented 1)}' tl'xe quanttrrn transfer rnatrix (QTIN/I) approach. XX7e introdtrce a unoregeneral faunily called '7'-ftrnctions and explore f'trnctior'xal rela.tions ll'11Ol1.& therm (T-system) aradtheir certain counbinations (Y-systerau). From their azaalytical property, xve derixze a closed set ofnon linear integral eqvrations which characterize tlae correlation lengtlu of' (c'cj.') at an5z finiteI?tetauperatures. Solvirag these eqttations tatrtaaerically, we explicitly detertaaine tlae correlatioralet'ugth, xvhich acctrrately coiuacides xvith jcrex'ious restrlts.
