JI JETP Lett. PY 1987 BP 285 EP 287 VL 46 IS 6 DE YBCO HTS HEB AB For the first time, measurements have been made on the electron energy relaxation time due to the electron--phonon interaction in films of the YBaCuO superconductor. The results indicate a significant intensification of the electron--phonon interaction in this compound as compared with normal superconducting metals. ER
