✦ Synopsis

Raman spectra of Yl-xCaxBa2Cu408 were investigated. At the Ca concentraiton of 10 %, which was solubility limit, frequency shift of 2 cm -1 was observed in the peaks at 492 cm -1 and 595 cm "1 assigned to the motion of 0(1) and 0(4) atoms, respectively. It is suggested that the stractural change due to the Ca substitution is too small to change the frequency, of the Raman peaks.
