Abstract
We have studied isotopes of element 104 formed by bombarding with and ions. and were positively identified by milking their daughters, and . is a 4.5-sec alpha-particle activity with a complex spectrum; is likewise an alpha emitter with a half-life of 3 sec. is tentatively identified as an 11-msec spontaneous-fission activity.
