Mesitylene is used as a moderator in compact accelerator-driven neutron sources. Therefore, the thermal neutron scattering law (TSL) data for mesitylene is important to develop a moderator and evaluate the performance by neutronics calculations. In this work, to validate the TSL data, the total cross section and double differential scattering cross sections in the range of several to tens of meV were measured at BL10 and BL14, respectively, at the MLF in J-PARC. Measured results were compared with evaluated values of JENDL-5 and JEFF-3.3.
