Presentation Transcript

  1. Cluster emission in ENSDF Alejandro Sonzogni National Nuclear Data Center Brookhaven National Laboratory E-mail: sonzogni@bnl.gov Brookhaven Science Associates

  2. Cluster Emission in ENSDF 223Ra 14C + 209Pb Mainly observed for nuclei heavier than Radium that decay to Pb isotopes. Process helped by large decay Q-values due to Z=82, N=126. ENSDF format doesn’t fully include cluster emission. Cluster radioactivity discovered in 1984 by Rose and Jones. Double proton emission is also not included in ENSDF Similar to alpha radioactivity.

  3. Cluster Emission in ENSDF Emitted nuclide in DSID Energy and intensity as comments DSID will be useful to parse 2P New format? Introduce K record, (C is already used) Like P record, before any level to specify cluster Similar to A, after a level Current format

  4. Cluster Emission in ENSDF Proposed action 1) Study the modification of the ENSDF format to fully account for cluster and double proton emission. 2) Perform cluster radioactivity horizontal evaluation to check for potential format conflicts. 3) Make changes in ENSDF codes and manuals by next NSDD meeting. 4) Next NSDD meeting would approve the new format.
