Neutron cross section according to its neutron cross section and how it reacts to an incident neutron. Nuclides that tend to absorb a neutron and either decay or keep the neutron in its nucleus are neutron absorbers and will have a "capture cross section" for that reaction. Isotopes that fission, are fissionable fuels and have a corresponding "fission cross section". The remaining isotopes will simply scatter the neutron, and have a "scatter cross section". Some isotopes, like uranium-238, have nonzero cross sections of all three. Isotopes which have a large scatter cross section and a low mass are good neutron moderators (see chart
How Many Clouds Can You See? a strange mixture of everything from free improvisation to calypso, his second date, 1970's "How Many Clouds Can You See?", is a much more focused affair. Surman clearly references one of his roots, John Coltrane, albeit on an instrument that the legendary saxophonist never played. All compositions by John Surman except where noted.
