    Focusing and selecting the HBr–N[sub 2]O cluster beam was performed by using a 2 m long electrostatic hexapole field. The observed focusing curve shows a clear evidence that the linear type HBr–N[sub 2]O isomer which has symmetry of symmetric top was preferentially detected in the...

    The active role of vorticity in the collision of a Lamb-like dipole with a no-slip wall is studied for Re values ranging between 625 and 20000. The initial approach of the dipole does not differ from the stress-free case or from a point-vortex model that incorporates the diffusive growth of the...
