Low-lying one-particle, two-hole (1p-2h) intruder bands which coexist with hole states are established in /sup 83/Se (N = 49) and are shown to exhibit properties similar to those of known intruder bands in odd-proton In (Z = 49) nuclei. Systematics of N = 49 nuclei show that /sup 83/Se (Z = 34) has the lowest-lying 1p-2h intruder state rather than midshell /sup 89/Zr (Z = 40) as would be expected by comparing with the In isotopes. We discuss the well established occurrence of intruder bands in odd-proton nuclei in contrast to the paucity of such bands in odd-neutron nuclei, and suggest that the Z = 40 and 64 subshell closures inhibit the core collectivity necessary for the lowering of particle states and formation of intruder bands in odd-neutron nuclei.
