Abstract

This is the first of a series of articles on delayed neutron spectrometry, in which neutron spectra are analysed for mass-separated isotopes. The theoretical basis is given for calculations of level densities, neutron energies and neutron emission probabilities. Delayed neutron spectra from the precursors 87Br and 137I are used to obtain a normalized set of level density parameters, which are then used to analyse the neutron spectra from 85As, 134Sn, 135Sb and 136Te.
