Abstract Platinum and gold have the similar crystal structure but different electronic affinities, as well as different effective electron densities near the implanted ions. Both the differences favour larger decay rate of ⁷Be in Pd than that in Au. We measured the variation of the decay rate of ⁷Be implanted in Pd and Au host materials. We have found that the decay rate of ⁷Be in Pd is larger than that in Au by 0.8%.
