【 摘 要 】

We extend the THSR wave function into N≠Z nucleon9Be and perform calculations for its ground state. The negative parity of the ground state is correctly described by the introduction of an extra phase factor. The calculation result of the ground state agrees well with other model. We also calculate the density distribution of the extra neutron. The molecular orbit structure of the extra neutron is found to be reproduced correctly with the THSR wave function without prior assumptions.
