A new Nd-loaded liquid organic scintillator based on pseudocumene (PC) solvent was developed for the experiment aimed at searching for 0 nu(II2)-I-2 decay of a Nd-150 nucleus. The optical characteristics of the scintillator were measured for several Nd concentrations. The measurements taken using two modules 1 and 2 m in length have made it possible to determine the effective attenuation length of the PC scintillator containing Nd (6.5 g/L). It was demonstrated that the scintillator characteristics remained unaltered over 1 year. The content of radioactive contamin
