description A history of the long controversy between Dubna and Berkeley concerning the discovery of the element 104 is given. In particular, the author reviews the difficulties associated with the use of spontaneous fission in detecting new elements and contrasts this method with the use of alpha particle activities to define the atomic number. Recent experiments at Dubna and Berkeley concerned with bombardments of /sup 246/Cm with /sup 18/O, /sup 248/Cm with /sup 16 /O, and /sup 249/Bk with /sup 15/N are compared in detail. The categorical conclusion is drawn that the Dubna claim that the isotope /sup 260/104 decays by spontaneous fission with a half life of 0.1 second is not valid. (14 refs).
