Quantum close-coupling scattering calculations of rotational energy transfer in the vibrationally excited CO due to collisions with He atom are presented for collision energies between 10−5 and 1000 cm−1 with CO being initially in the vibrational level =2 and rotational levels j=0,1 ,4, and 6. The He–CO interaction potential of Heijmen et al. J. Chem. Phys. 107, 9921 1997 was adopted for the ca...

energy of a moving gas into rotational energy. At a given flow rate Q, the rotor of the turbine meter would spin at an angular velocity ωi as shown in Figure 1. With an idealized turbine meter, the rotational speed of the rotor would be directly proportional to the volumetric flow rate of the flowing medium. The relationship between flow rate Q and the angular velocity ωi can be expressed as fo...

, i.e. just above the dissociation threshold, was carefully examined. Rotational distribution observed was compared with statistical one calculated by phase space theory. Two distinct types of rotational distributions were found; one of them exhibits non-statistical distribution while the other is statistical one expected by phase space theory. In the case that a vibronic energy of the initial ...

We show that the Nambu-Goldstone formalism of the broken gauge symmetry in the presence of the T=1 pairing condensate offers a quantitative description of the binding-energy differences of open-shell superfluid nuclei. We conclude that the pairing-rotational moments of inertia are excellent pairing indicators, which are free from ambiguities attributed to odd-mass systems. We offer a new, unifi...

Results of 2D simulations of the magnetorotational mechanism of su-pernova type II are presented. Amplification of toroidal magnetic field of the star due to differential rotation of the star leads to the transformation of the rotational (gravitational) energy to the energy of the supernova explosion. In our simulation the energy of the explosion is 1.12 · 10 51 erg. The explosion ejects about ...

friction welding is widely used in various industries. in friction welding, heat is generated by conversion of mechanical energy into thermal energy at the interface the work pieces during pin rotation under pressure. a three-dimensional thermo mechanical simulation of friction stir welding (fsw) processes is carried out for aluminium alloys of 6061and 7050 where the simulation results are comp...

We have performed a crossed molecular beam velocity-map ion imaging study of state-to-state rotational energy transfer of NO(A2Σ+, v = 0, N = 0, j = 0.5) in collisions with N2 and have measured rotational angular momentum polarization dependent images of product NO(A) rotational levels N' = 3 and 5-11 for collisions at an average energy of 797 cm-1. We present an extension of our previously pub...

We evaluate the shifts imparted to vibrational and rotational levels of a linear molecule by a nonresonant laser field at intensities of up to 10(12) W/cm(2). Both types of shift are found to be either positive or negative, depending on the initial rotational state acted upon by the field. An adiabatic field-molecule interaction imparts a rotational energy shift which is negative and exceeds th...
