High spin states in 71Ga

Excited states in the odd-A nucleus 71Ga have been studied via the 70Zn(7Li, \\begin{document}$ \\alpha2n $\\end{document} )71Ga fusion-evaporation reaction with incident beam energies of 30 and 35 MeV. The level scheme is established up to spin \\begin{document}$ I^{\\pi} $\\end{document} = (29/2+) and excitation energy \\begin{document}$ \\sim $\\end{document} 6.6 MeV. A previously known sequence built on the 9/2+ state is extended as a new rotational band originating from the \\begin{document}$ \\nu (g_{9/2}^2) $\\end{document} alignment. Additionally, negative-parity sequence is also reported. The observed energy levels of 71Ga have been interpreted in the framework of nuclear shell model (SM).
