About two months ago Albert Alberts, from Netherlands, mentioned some observations made by Otto Reifenschweiler. This was on the restricted Internet list for CMNS researchers. Asked for a clarification, Alberts wrote:
“The ‘Reifenschweiler effect’ is the observation that the beta-decay of tritium half-life 12.5 years is delayed reversibly by about 25-30% when the isotope is absorbed in 15 nm titanium-clusters in a temperature window in between 160-275 C. Remarkably at 360 C the original radioactivity reappears. The effect is absent in bulk metal. Discovered around 1960/1962 at Philips Research Eindhoven, The Netherlands Reifenschweiler extensively discussed his observation with o.a Casimir (the director of research at the time), Kistemaker (ultracentrifuge expert), and although no satisfactory explanation was found, R. was allowed to publish it. At the time a unique example as to how an electronic environment might affect nuclear phenomena.”
In a private e-mail message Alberts, who used to be a physics teacher, wrote: “I don’t know if that work was replicated, he was invited to, I think, Sandia and later to Los Alamos to demonstrate the effect, instigated by a fellow named Cox. What I do know is that it was replicated in the Philips labs many times, supervised by the eminent Casimir at the time. The beta-rays were detected by Geiger-Mueller counters, at the time Philips had the most advanced evaporation/evacuation techniques possible. Even electron microscopy. The work was criticized by a German fellow, but Reifenschweiler retaliated. That stuff should be in his reprints.” He also wrote that he is in contact with Dr. Reifenschweiler (who is quite old) and that he has some old manuscripts. Subsequently I asked Alberts to compose an essay on Reifenschweiler effect. He agreed. His essay will be shown below as soon as it arrives. I think Reifenschweiler himself will assist in writing a good summary. Meanwhile let me mention that a French researcher, Fabrice David, also summarized Reifenschweiler effect in 2004. That was the topic of his presentation at ICCF11 (11th International Conference on Cold Fusion) in Marseilles.
ALBERTS’ ESSAY WILL BE PLACED HERE
