Isolated-core-excitation (ICE) scheme and autoionization detection are employed to study the bound Rydberg states of europium atom. The high-lying states with odd parity have been measured using the autoionization detection method with three different excitation paths via 4F76s6p[sP5/2], 4f76s6p[sP7/2]and 4s76s6p[sP9/2]intermediate states,s respectively. In this paper the spectra of bound Rydberg states of Eu atom are reported, which cover the energy regions from 36000 cm-1 to 38250 cm-1 and from 38900 cm-1 to 39500 cm-1. The study provides the information about level energy, the possible J values and relative line intensity as well as the effective principal quantum number η* for these states. This work not only confirms the previous results of many states, but also discovers 11 new Rydberg states of Eu atom.
