  We study the effect of focusing of the radially and azimuthally polarized
vector beams on the spin angular momentum (SAM) density and Poynting vector of
scattered waves from a Mie particle. Remarkably, the study reveals that the SAM
density of the scattered field is solely transverse in nature for radially and
azimuthally polarized incident vector beams; however the Poynting vector shows
usual longitudinal character. We also demonstrate that the transverse SAM
density can further be tuned with wavelength and focusing of the incident beam
by exploiting the interference of different scattering modes. These results may
stimulate further experimental technique of detecting the transverse spin and
Belinfante's spin-momentum densities.
