The yrast states were observed up through both the first and second band crossings in both 112Ru and 116Pd using the 238U(α, f) fusion–fission reaction. The rotational alignment of the g9/2 proton-pair is responsible for the second band crossing. This assignment is based on the amount of angular momentum gained in the alignment and a similar crossing frequency is observed for the rotational ban...

Rotationally resolved spectra ofthe 66 and 66 1Ö band of benzene, C6H6, in a supersonic molecular beam at rotational temperatures between 8 and 50 Kare reported. The spectra consist oflines of 85 MHz linewidth. An unexpectedly low saturation intensity of ::::; 10 W /cm is found for the observed one-photon transitions, and it is shown that the saturation intensity differs for different rotationa...

Topological Chern indices are related to the number of rotational states in each molecular vibrational band. Modification of the indices is associated to the appearance of "band degeneracies," and exchange of rotational states between two consecutive bands. The topological dynamical origin of these indices is demonstrated through a semiclassical approach, and their values are computed in two ex...

2014 The odd-odd 158Ho nucleus is studied by means of the reactions 159Tb(03B1, 5n)158Ho and 160Dy(p, 3n)158Ho. The life-time of an isomeric state is measured as T1/2 = (29 ± 3) ns. A rotational band is developed up to spin 16-. LE JOURNAL DE PHYSIQUE LETTRES Classification Physics Abstracts 4.220 4.240 TOME 37, SEPTEMBRE 1976,

In an effort to understand the low temperature behavior of recently synthesized molecular magnets we present numerical evidence for the existence of a rotational band in systems of quantum spins interacting with nearest-neighbor antiferromagnetic Heisenberg exchange. While this result has previously been noted for ring arrays with an even number of spin sites, we find that it also applies for r...

It is very interesting to probe the rotational symmetry of semiconductor quantum dots for quantum information and quantum computation applications. We studied the effects of rotational symmetry in semiconductor quantum dots using configuration interaction calculation. Moreover, to compare with the experimental data, we studied the effects of hidden symmetry. The 2D single-band model and the 3D ...

A highly-deformed rotational band has been identified in the N = Z nucleus 36 Ar. At high spin the band is observed to its presumed termination at I π = 16 + , while at low spin it has been firmly linked to previously known states in 36 Ar. Spins, parities, and absolute excitation energies have thus been determined throughout the band. Lifetime measurements establish a large low-spin quadrupole...

Only a single linearly dispersing π-band cone, characteristic of monolayer graphene, has so far been observed in Angle Resolved Photoemission (ARPES) experiments on multilayer graphene grown on C-face SiC. A rotational disorder that effectively decouples adjacent layers has been suggested to explain this. However, the coexistence of μm-sized grains of single and multilayer graphene with differe...
