✦ Synopsis

We have measured the velocity and attenuation of longitudinal and transversal sound in ceramic Bi2Sr2CuO6 samples. The velocities and most of the moduli do not exhibit significant unregularities in the temperature range investigated. Their absolute values are low in comparison with other oxide superconductors. The attenuation has a maximum near 250 K.

Superconducting energy gaps in Bi2Sr2\_xNdxCuO6+y (0 ~< x~< 0.7 ) with T¢ = 6.5-20 K have been studied by the electron tunneling technique. The smallest gap value was found at \_+ 2 meV for x= 0 with T¢ = 6.5 K. The obtained gap values almost scale with x and thus T~ throughout the superconducting p
