Description
A search was made with a sea water sample taken at a depth of 4000 m for anomalously heavy hydrogen dating from the early Universe. A technique of accelerator mass spectrometry involving a time-of-flight spectrometer was used. A new upper limit for the concentration of heavy particles in hydrogen is set around 4x10-17 in the mass range of 5--1600 u at a 95% confidence level
