Leeds University 1973
Nelson Mandela had a nuclear particle named after him, by a British University, Leeds, in 1973.
Dr. E. W. Kellerman, Dr. G. Brookes and Dr. J. E. F. Baruch predicted the existence of a particle 40 to 70 times the mass of a proton.
Later, a team from Durham University could not replicate the measurements.
Does it exist?
