A comparison of diamonds irradiated by high fluence neutrons or electrons, before and after annealing
T Hainschwang, A Respinger, F Notari… - Diamond and related …, 2009 - Elsevier
Neutron-and electron-irradiated type Ia “black” diamonds were analyzed: three near
colorless type Ia diamonds were treated in a nuclear reactor with a dose of 1.8× 1017
neutrons/cm2 and three equivalent samples were irradiated in an electron accelerator with a
dose of approximately 0.5 GGy 10 MeV electrons. The diamonds were then annealed and
analyzed after the different steps of the treatment. The samples turned from near colorless to
very dark green to opaque black upon irradiation and deep greenish yellow to deep orangy …
