✦ Synopsis

We study virtual states in 5 He and 10 Li by using the Jost function method (JFM). In 5 He, we obtained an s-wave pole with the complex energy E = 7.50 -44.7i MeV using a 4 He-n potential called KKNN. In 10 Li, we investigated s-wave virtual poles with the 9 Li-n interaction microscopically constructed by taking into account the Pauli-blocking effect. We obtained a virtual state at E = -0.135 MeV (k = -0.077i fm -1 ). The attractive property of the s-wave 9 Li-n potential for 10 Li is discussed in comparison with the 5 He ( 4 He + n) system and also calculational results for the 9 Li-n potential of Thompson and Zhukov.
