Magnetic Moments of Light Hypernuclei with the pmnkY Configuration (Y= ,   and  )

With the use of the effective momemt method, we calculate magnetic moments of light hypernuclei, assuming shell model wave functions with good isospin. The following systems are investigated ; [I] nY and pY systems, [II] pnY systems, [III] pn2Y and p2nY systems and [IV] p2n2Y systems, where p and n show a proton and a neutron, and Y denotes Λ -, Σ - and Ξ -hyperon, respectively. The results for p -shell Λ -hypernuclei are compared with the theoretical values obtained by T. Motoba et al., who used the three-cluster [α- x - Λ ] model ( x = n , p , d , t , 3 He or α). Dynamical effects on hypernuclear magnetic moments are also discussed using the configuration mixing theory. We briefly comment on magnetic moments of sd - and pf -shell hypernuclei.
