Description

We observed the 19 keV neutron decay from the 3.388-MeV state of /sup 12/B by measuring /sup 11/B-neutron coincidences in colinear geometry at several angles. The ratio of this yield to the yield of particle-stable /sup 12/B nuclei is a measure of the excitation energy of /sup 12/B fragments produced in the reaction. The extreme kinematic focusing of the 19-keV decay enabled us to obtain the dependence of this ratio on fragment kinetic energy. For /sup 12/B nuclei emitted with kinetic energies E/Aapprox. <15 MeV the ratio is surprisingly constant; for /sup 12/B nuclei of higher kinetic energy it decreases monotonically
