Neutron-rich Lambda hypernuclei:

structure and production.


Abstract:

     Properties of light neutron-rich L hypernuclei (12LBe, 16LC) are calculated within the Skyrme-Hartree-Fock approach. 

    Interplay between hypernuclear interaction features and properties of these hypernuclei is studied. 

      The production of this hypernuclei by (K-,p+) and (p-,K+) reactions is considered.  

     Two different production mechanisms should be treated: the two-step process with meson charge exchange (e.g., p-p ® p0n, p0p ® K+L and p-p ® K0L, K0p ® K+n), and the one-step production (p-p ® K+S-). In the last case, the reaction proceeds via a small S-component, arising in L hypernuclei due to LN-SN coupling, as a doorway state.
