Argonne and FRIB team narrows krypton-88 neutron-capture rate, closing strontium gap in stellar models

Argonne and FRIB researchers have measured the krypton-88 neutron-capture rate for the first time, cutting its uncertainty from eightfold to threefold. Updated i-process models with the lower rate produce more strontium, closing a long-standing gap with old-star observations.
