摘要：

We have studied isotopes of element 104 formed by bombarding Cf249 with C12 and C13 ions. 104257 and 104259 were positively identified by milking their daughters, No253 and No255. 104257 is a 4.5-sec alpha-particle activity with a complex spectrum; 104259 is likewise an alpha emitter with a half-life of 3 sec. 104258 is tentatively identified as an 11-msec spontaneous-fission activity. © 1969 The American Physical Society.
