Candidate-nuclei for observation of a bound dineutron. Part II: The (n,2n + n) and (γ,2n) nuclear reactions
This is a second part of a survey for stable isotopes in the mass range 90 < A < 210, to find candidates showing the bound dineutron nuclear reaction output channel after irradiation with neutrons or photons. To this end, the neutron capture reaction cross sections were calculated in the (0 - 30) MeV energy range with the TALYS-2.0 code for nuclei in the outgoing channel, which are expected to host bound dineutrons. This study was performed to find appropriate candidates to observe bound dineutron decay meeting the criteria based on the (n, γ) resonance cross section analysis. This study opens up a new direction in dineutron research with the (n, +n) and (γ, ) nuclear reactions.
