      The fragmented neutron states in145,147,149Nd detected through144Nd(d, p) and148,150Nd(d, t) reactions can be accounted for in terms of quasiparticles coupled with anharmonic vibrator model. The wave functions, obtained from diagonalisation of the Hamiltonian matrices are utilised to calculate B(E2), B(M1) and branching ratios in145,147Nd. The calculated results are discussed in the light of the recent experimental findings.

      The high resolution (3He,α) reaction on206Pb shows the distribution of the 2f7/2, 1h9/2 and 1i1 3/2 neutron states of205Pb within the 6 MeV excitation energy of205Pb. The spectrum of these three-hole states is obtained within the hole-core vibrational coupling scheme. The shell model energies of the neutron hole states arising from the core-polarization effect are compared with the Bansal-French energy weighted sum rule. The possible implication of the present neutron hole energies has been discussed in the light of the deduced shell model wave functions of the collective states of206Pb.
