Spectroscopy of 142Nd and 143Nd via inelastic proton scattering at Ep = 25 MeV

Crossing of the high-spin members of the and multiplets in

“…A rather complete picture emerges from the combined results of structure-selective reactions for inelastic scattering and non-selective compound nucleus experiments. Previous studies of this kind have been performed, for example, in the double-magic lead region-209 83 Bi 126 and 207 82 Pb 125 [1]-and in the magic N = 82 region-143 60 Nd 83 [2]. Whereas in the double-magic ± particle nuclei the level density around the energy of the octupole multiplet is quite low, the single-magic ± particle nuclei have the advantage of avoiding noticeable effects of the Pauli principle and exhibiting an increased richness of configurations and configuration mixing.…”

“…Also given are the only two other L = 3 states that have cross sections larger than 80 µb sr −1 at maximum (spin 7/2 − -9/2 − ). The β 3 values and isoscalar transition rates G 3 given are calculated with the usual procedure (see, for example, [2]). Due to problems with the current integrator during the (d, d ) experiments, we cannot exclude the possibility that the absolute cross sections and hence β 3 values for the In and Sn states are affected by systematic errors.…”
