The two-neutron transfer reaction 147Sm(p,t)145Sm was studied at Ep=26 MeV. Angular distributions were measured for θlab=5°–50°. The strength of the two neutron monopole pairing phonon⊗particle configuration (n-=1,n+=1)⊗ν2f7/2 is identified in odd mass 145Sm and is found to be quasi-uniformly spread in two narrow groups of as many as 8+5=13 states. This unexpected large fragmentation is compared with the one in the core nucleus 144Sm and with that from its isotone 143Nd where the monopole pairing vibration is less fragmented. The couplings with other excitation modes are extracted.
