    "abstract": "We apply a large-scale shell model to the study of proton-rich odd-mass\nnuclei with $N \\approx Z$. Calculations predict unexpected structure in the\n$^{69}$As nucleus for which a detailed experiment was recently performed. In\nthis odd-proton nucleus, one neutron competes with one proton for occupying the\nhigh-$j$ intruder orbit $g_{9/2}$ in the $9/2_1^+$ state and almost solely\noccupies the $g_{9/2}$ orbit in other low-lying positive-parity states. The\nT=0, J=9 one-proton-one-neutron alignment takes place in the negative-parity\nstates with medium-high spins. A unique coexistence of two lowest bands with\npositive and negative signs of spectroscopic quadrupole moments is predicted.",
