We have measured deexcitation rays for the first time in the neutron-rich nuclei of 
Pu
and 
Pu
produced by the (
O, 
O) and the (O, 
O) reactions, respectively. The ground-state band of Pu was established up to 12
states. The systematics of the moments of inertia of 
Pu isotopes suggests that the deformed subshell closure disappears in these isotopes. The measurements of deexcitation rays in Pu shows a small energy spacing between neutron orbitals at , which explans the disappearance of the subshell closure.
