Palladium powders had been aged at room temperature for 6.6 years. The 3He content was estimated from the initial tritium stoichiometry and the aging time by applying the radioactive decay law, which shows the helium-palladium atomic ratio (He/Pd) is 0.204. Tritium absorption of aged palladium powder has been measured in the initial pressure of 284 kPa and as a comparation, fresh palladium...
