A new isomer with a half-life of 23.0(8) ms has been identified in
Pd at 2406 keV excitation. The proposed spin and parity configuration is 10
, with maximally aligned configuration of two 
neutron hole.
-decay from the long-lived isomer was also observed to populated excited states at high spins in
Ag. The small energy difference between the 10
and 7
isomers in
Pd was interpreted in the frame of the monopole shift of the 1
neutron orbit. The effects of the monopole interaction on the evolution of single-neutron energies below
Sn are discussed in terms of central and tensor forces.
