Autor: J. Romero-Barrientos, F. Molina, J.I. Márquez Damián, M. Zambra, P. Aguilera, F. López-Usquiano, S. Parra

Publikováno v: Nuclear Engineering and Technology, Vol 55, Iss 5, Pp 1593-1603 (2023)

In deterministic and Monte Carlo transport codes, β-delayed emission is included using a group structure where all of the precursors are grouped together in 6 groups or families, but given the increase in computational power, nowadays there is no re
