    Lee, Choochon2011

    … 99.9999% purity were irradiated with 3 MeV electrons near liquid nitrogen temperature. The damage production rate is found to depend on the purity of the specimen giving a lower value for the high purity specimens. It is also found that the production rate is reduced remarkably by quenching …
