Precise measurement of hyperfine structure in the state of Li using saturated-absorption spectroscopy
We report a precise measurement of the hyperfine interval in the
state of Li. The transition from the ground state ( line) is
accessed using a diode laser and the technique of saturated-absorption
spectroscopy in hot Li vapor. The interval is measured by locking an
acousto-optic modulator to the frequency difference between the two hyperfine
peaks. The measured interval of 92.040(6)~MHz is consistent with an earlier
measurement reported by us using an atomic-beam spectrometer [Das and
Natarajan, J.\ Phys.\ B {\bf 41}, 035001 (2008)]. The interval yields the
magnetic dipole constant in the state as , which is
discrepant from theoretical calculations by ~kHz.Comment: 5 pages, 3 figure
Graphene/Li-Ion battery
Density function theory calculations were carried out to clarify storage
states of Lithium (Li) ions in graphene clusters. The adsorption energy, spin
polarization, charge distribution, electronic gap, surface curvature and dipole
momentum were calculated for each cluster. Li-ion adsorbed graphene, doped by
one Li atom is spin polarized, so there would be different gaps for different
spin polarization in electrons. Calculation results demonstrated that a smaller
cluster between each two larger clusters is preferable, because it could
improve graphene Li-ion batteries; consequently, the most proper graphene anode
structure has been proposed.Comment: 19 pages, 7 figures, 1 tabl
