First Allowed Bandcrossing in Neutron Deficient Nucleus 141 Tb
نویسنده
چکیده
The neutron deficient Tb nucleus has been studied with the Mo (Fe, αp) reaction at 240-MeV incident energy and the multidetector array GASP. For the yrast πh11/2 decoupled band, excited states up to 6.7 MeV and spin up to 47/2− have been observed. This band presents an upbend at rotational frequency of ~ω = 0.38 MeV due to the alignment of h11/2 protons. The results are discussed in terms of the Cranking model.

Rotational alignment near N=Z and proton-neutron correlations
The effects of the residual proton-neutron interactions on bandcrossing features are studied by means of shell model calculations for nucleons in a high-j intruder orbital. The presence of an odd-nucleon shifts the frequency of the alignment of two nucleons of the other kind along the axis of rotation. It is shown that the anomalous delayed crossing observed in nuclei with aligning neutrons and...

متن کاملProperties of neutron emission in fission processes induced by 20 Ne + 159 Tb and 20 Ne + 169 Tm reactions between E = 8 and 16 MeV / nucleon
Neutron emission in E=8, 10, 13, and 16 MeV/nucleon 20Ne+ 159Tb, 169Tm induced fission reactions has been further studied. The 4p configuration of the DEMON neutron multidetector allowed a detailed investigation of the preand postscission properties as functions of the fission parameters. The emission of the neutrons from their respective sources was found to be isotropic to a high degree. The ...
متن کاملAb initio calculations as a quantitative tool in the inelastic neutron scattering study of a single-molecule magnet analogue.
Ab initio calculations carried out on the Tb analogue of the single-molecule magnet family Na9[Ln(W5O18)2] (Ln = Nd, Gd, Ho and Er) have allowed interpretation of the inelastic neutron scattering spectra. The combined experimental and theoretical approach sheds new light on the sensitivity of the electronic structure of the Tb(III) ground and excited states to small structural distortions from ...
