Static properties of the 9Be nucleus in the ground and excited states in the cluster model

The ground-state static observables and elastic longitudinal (charge) form factors of the 9Be nucleus in the ground and excited states are considered. The calculations were performed in the framework of the dynamic three-particle 2 + n-model of the 9Be nucleus with the Pauli projection. The ground state of the 9Be nucleus has been calculated in two models distinguished by the - interaction-model 1 (Ali-Bodmer potential) and model 2 (Buck-Friedrich-Wheatley potential). For the excited states of 9Be, wave functions with Ali-Bodmer potential for the - interaction are utilized.
