NEW APPROACHING IN NEUTRON ABSORPTION ON THXSR2O1.8 NANO MATERIAL STRUCTURE WITH QUANTUM DOT AT MAGNETIC QUADRUPOLE ENHANCEMENT
ABSTRACT: We present
a theoretical investigation
of ThxSr2O1.8 nano
material structure with
quantum dot interacting with
a strongly localized
optical field as
encountered in high-resolution near-field optical microscopy.
The strong gradients
of these localized
fields suggest that
higher-order multipolar interactions will affect the standard magnetic dipole
transition rates and selection rules. For
neutron tunneling quantum
dot in the
strong confinement limit
we calculated the
interband magnetic
quadrupole absorption rate
and the associated
selection rules. Founded
that the magnetic quadrupole
absorption rate is
comparable with the
absorption rate calculated
in the magnetic dipole approximation.
This implies that near-field optical techniques can extend the range of
spectroscopic measurements for 412 MHz at quantum magnetic field until 515 MHz
deployment quantum field at B around 375-450 tesla beyond the standard dipole
approximation. However, we also
show that spatial
resolution cannot be
improved by the
selective excitation of
electric quadrupole transitions.
