Abstract
The Peierls conductor o-TaS3 enriched with isotope (34S (99%)) has been synthesized. The temperature and electric field dependencies of the conduction of these samples were studied. The results were compared with ones for samples of the same quality with natural isotope composition. The following parameters of the linear conduction were extracted : the Peierls transition temperature (Tp), the width (δTp) and height of the peak of temperature derivative of conduction, activation energy (Δ). Small increase of the Peierls transition temperature by 1 ± 1 K was observed in Ta34S3 samples.
