p-shell {lambda} hypernuclei with the Nijmegen ESC04 baryon-baryon potential
- Department of Physics, Western Michigan University, Kalamazoo, Michigan 49008 (United States)
The spectra of seven p-shell {lambda} hypernuclei are calculated with effective interactions derived from the new Nijmegen ESC04 baryon-baryon interaction. The results of interactions ESC04A and ESC04B compare well with the known experimental levels, whereas those of ESC04C and ESC04D do not. The primary difference between the two pairs of potentials is the ratio of triplet to singlet strength in the central potential. The {sub {lambda}}{sup 16}O results indicate that the tensor interaction is too weak and/or the spin-orbit odd interaction is too strong for all potentials. In addition the {lambda}N-{sigma}N coupling potentials have an unusual radial behavior. The calculations provide a natural explanation for the reduction of the spin-spin interaction of phenomenological interactions from the beginning to the end of the shell.
