Purdue Researchers Reproduce Taleyarkhan Sonofusion Results

Xu and Butt

Researchers at Purdue University have reproduced sonofusion results reported by Rusi Taleyarkhan. The results, replicated by researchers Xiban Yu and Adam Butt, were published in the May issue of the peer-reviewed journal Nuclear Engineering And Design. Yu and Butt are now working with Taleyarkhan in his Oak Ridge lab, but were not prior to the publication of their paper.

Update 7/17: An article appearing in includes comments by Seth Putterman, Taleyarkhan's nemesis, who raises his earlier objection of inadequate detection:

Professor Seth Putterman from the Californian University at Los Angeles thinks, that "the data that [Xu and Butt] presented in the paper is not convincing basically for the same reason as all of Taleyarkhan's papers." Putterman demands a timed coincidence between flashes of light due to sonoluminescence and neutron measurements in a time window of a billionth of a second. Taleyarkhan's group had only shown a correlation to be within a 2 millisecond window.
