Monochromatization is not needed in echo techniques ( neutron spin echo, neutron resonance spin echo ), which use the quantum mechanical phase of the neutrons in addition to their amplitudes.
2.
At the end, Hutchman realises that rather than to the elimination of nuclear weapons, his invention just led to further investments in them, to create new bombs impervious to neutron resonance.
3.
These concentrate on much more specialised topics than in the case of Type B Conferences ( e . g . angular correlations, lifetime measurements, neutron resonance studies in the field of Nuclear Physics ).
4.
However, this simple model does not take into account so called neutron resonances, which strongly modify neutron cross section in energy range of 1 eV 10 keV, nor threshold energy of some nuclear reactions.
5.
It has neutron resonances that prevent almost all moderation at energies below 0.14 eV . Zirconium deuteride is superior, because it has a lower neutron absorption cross-section than aneutronic hydrogen, decreasing neutron absorption in a reactor.
6.
The plot follows the main character, Lucas Hutchman, an " undistinguished mathematician ", who invents a machine that may detonate virtually instantaneously every nuclear bomb in the world, by inducing a " self-propagating neutron resonance ".
