摘 要: | We have measured the possible change of the decay rate of ^7Be implanted into hosts of natural beryllium and natural gold. No difference between the ^7 Be decay rates in the two hosts is observed within the experimental precision of 0.12%. This result implies that change of the decay rate of ^7Be implanted in different materials cannot be simply expected from the electron affinity difference consideration lonely and the lattice structure of the host materials should be taken into account.
