Abstract
Superconducting transition temperatures of and have been measured in the composition ranges and , respectively. Hydrogen or deuterium absorption is found to decrease of . Pronounced isotope effects have been observed. At , hydrogen absorption reduces by 4.8 K while deuterium absorption reduces by 6.9 K with respect to .
