The Sigma Xi society will recognize Brigham Young University physics professor Steven E. Jones on Thursday at its annual awards lecture.

The lecture, which is free to the public, will begin at approximately 8:30 p.m. in Room 321 Wilkinson Center following Sigma Xi's banquet. Jones will speak on "Cold Fusion: What It Is and What It Isn't" and explain BYU's most recent cold fusion experiments.He will also discuss recent developments in the Pons-Fleischmann story.

"On March 23, 1989, two chemists from the University of Utah stunned the world by announcing in a press conference that they had achieved sustained nuclear fusion in a test tube," says Jones. "They claimed that the excess heat so produced could provide clean fusion energy."

Meanwhile, Jones and other BYU professors had been conducting cold nuclear fusion research since early 1986 using various metals immersed in a bath of heavy water. The process superficially looked similar to the Pons-Fleischmann test-tube work.

"In reality, the approaches and the results are vastly different," Jones says.
