  We discuss the excitation of a chiral dipolar mode in an achiral silicon
nanoparticle. In particular, we make use of the electric and magnetic
polarizabilities of the silicon nanoparticle to construct this chiral
electromagnetic mode which is conceptually similar to the fundamental modes of
3D chiral nanostructures or molecules. We describe the chosen tailored
excitation with a beam carrying neither spin nor orbital angular momentum and
investigate the emission characteristics of the chiral dipolar mode in the
helicity basis, consisting of parallel electric and magnetic dipole moments,
phase shifted by $\pm \pi/2$. We demonstrate the wavelength dependence and
measure the spin and orbital angular momentum in the emission of the excited
chiral mode.
