Ternary to binary light charged particle yield ratio
CP-N/44, 4C-4/114, CP-D/599

Ternary alpha and triton emission probabilities in neutron-induced and spontaneousfission have measured by C. Wagemans and their colleagues. In EXFOR, 5 articles[1-6] are considered as the sources of numerical data. They have denoted ternary(long-range) alpha and triton emission probabilities in fission by LRA/B and t/B, andthey has been coded as---(-,F),TER/BIN,FY/RAT,A---(-,F),TER/BIN,FY/RAT,T. However, Dr. O. Serot (CEA Cadarache) explains the definition of the probability as“Counting rate of Ternary alphas particles (or tritons) emitted during fission, LRA(or t), divided by counting rate of all fission events (Binary + Ternary fissions, B)”, even though B in their notation denotes “Binary fission”. Therefore their data should
be coded with---(-,F)2-HE-4,TER,FY---(-,F)1-H-3,TER,FY
for LRA/B and t/B, respectively.
Because there is no other subentry coded with TER/BIN,FY/RAT the following
update of dictionary is also proposed:

List of data compiled with “TER/BIN,FY/RAT” in EXFOR(10 and 10-4 should be multiplied to alpha and triton emission data, respectively).
- Bold font means we need additional correction.
- 22896: 257Fm(SF) data in Table 2 of [3] is missing and should be added.
- 22900: 007-018, 028-044 are not from experiments, but from empirical formula.
