Abstract
Superconducting energy gap of CeRu2 has been measured by break-junctio n tunneling. The gap value of 4 Delta = 5.1 meV at 2.4 K for a superco nductor-insulator-superconductor (SIS) tunneling with T-c = 6.7 K give s the ratio 2 Delta(0 K)/k(B)T(c) = 4.4, thereby indicating a strong-c oupling superconductor.
