Energy levels in 142Nd

The excited states of ¹⁴²Nd were studied by means of the decay of 40 sec ¹⁴²Pm and the ¹⁴²Nd(p, p') reaction via isobaric analog resonances. Approximately sixty levels of ¹⁴²Nd were observed below 5.3 MeV excitation, including several neutron particle-hole states excited strongly in (p, p') at f_{$\text{7}\text{2}$}, p_{$\text{3}\text{2}$}, p_{$\text{1}\text{2}$} and f_{$\text{5}\text{2}$} analog resonances. We have collected together all known energy levels in ¹⁴²Nd and have proposed J^π assignments for 22 excited states. We have also compared the experimental level spectrum (positive-parity states only) with a calculated one based on the shell model.
