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
The Lion has Many Ears of jealousy; that Guðrún's son Svenni stole the antique pistol; that Kjartan in fact killed himself, staging his suicide as a murder (echoing how in "Laxdæla saga" Kjartan refuses to defend himself against Bolli); and that Hrefna murdered Bolli, apparently supposing that he was to blame for Kjartan's murder. In an epilogue, Guðrún bumps into Leó in the street and it becomes clear from family resemblance that her son Þorlákur is in fact not Bolli's son, but Leó's, and the two become a happy couple, echoing Guðrún Ósvifursdóttir's fourth marriage, to Þorkell Eyjólfsson, in "Laxdæla saga".
