OBSERVED BRANCHING RATIOS OF ALPHA-FRAGMENTS TO FISSION-FRAGMENTS OF CF-252 USING CR-39

There has been a rapid growth in the application: of SSNTD to the stud y of nuclear phenomena in the recent past. The considerable ease intro duced in recording the signature of heavy ions in the presence of alph a particles has made them particularly suitable for the study of spont aneous fission of transuranic elements. It is the object of the presen t study to explore the response of CR-39 for the determination of the branching ratios of alpha to fission fragments of Cf-252 at the end of almost one and four half-life periods for alpha decay. The results mo re or less confirm the expected values; (C) 1998 Elsevier Science Ltd. All rights reserved.
