Abstract：
The isomeric absolute cross-section have been measured for the reaction ¹³³Cs (n,c) ¹³⁴Cs at 14.8 MeV neutron energy.The results are:σ _n,γ ^134mCs=1.76±0.14mb;σ _n,γ ^134gCs=5.17±0.41mb;σ _n,γ ^134+gCs=6.93±0.55mb.The isomeric cross-section ratio is σ ^134m _Cs/σ ^134gCs=0.34±0.03 The experimental results are in agreement with the values given by S.M. Qaim andcompared with the theoretical results calculated by Huizenga-Vandenbosch theory.From this, the spin cut-off paramenter σ and the number of γ-Cascades have been de-termined.
