Structure Analysis of Light [I] - Hypernuclei
- In this research work, the binding energies of light ; hypernuclei namely ; - 12C, ; - 14N and ; - 16O have been calculated within the frame work of ; single-particle model by solving nonrelativistic Schrödinger equation. In this calculation, the Gaussian basis wave function and phenomenological Woods-Saxon central potential including coulomb interaction are used. By using the strength of Woods-Saxon potential -14.0 MeV, the calculated bound state energy of ; - 14N is 3.07 MeV over binding than the recent experimental results, 4.38 r 0.25 MeV which is observed from E373 experiment, KEK, Japan. Therefore, the binding energies of ; - 14N have investigated by varying potential strength. At the potential depth -8.5 MeV, the calculated binding energy of ; - 14N is in good agreement with the experimental result. Therefore, this potential strength is applied to study the structure analysis of other two light ; hypernuclei. The observed binding energies of 1S state for ; - 12C and ; - 16O are 3.64 MeV and 5.09 MeV respectively. In addition, the root-mean-square radii of these light ; hypernuclei have also investigated. The calculated results are 3.24 fm for ; - 12C, 3.11 fm for ; - 14N and 3.02 fm for ; - 16O respectively. It is also found that 3D and 4F states are only pure ; - atomic states while the other S and P states are Coulomb-assisted nuclear ; -bound states called hybrid states.
