An experiment was carried out to find out the palarization of electrons by double scattering. The scatterers used were gold foils of 5×10
−5 mm thick and the energy of electrons ranged from 45 to 92 kev. The scattering angle at the first foil was taken as 90 degrees and that at the second foil 78 degrees. Polarization effect, as predicted by Mott, has been found, though its magnitude was somewhat smaller than that given by the theory. The values of 200 δ obtained was 3.6±1.0, 4.0±0.9, 6.8±0.7, 9.0±0.6, and 9.1±1.0 for the electrons of energy 45, 60, 70, 90, and 92 kev, respectively.

The electrostatic energy matrices of the configurations
d4p,
d5p and
d6p were calculated by Racah’s method of tensor operators. The results for the last configuration were compared with the observed values by J. C. Dobbie for Fe II, 3
d64
p.

Racah’s theory of the structure of the equivalent electron groups was applied to the
fn configurations. The coefficients of fractional parentage of
f3 terms were determined in this paper, and the electrostatic energies were re-calculated in
vα
SL scheme

Utilizing the C.F.P. for
f3 terms obtained in the preceding article, the matrices of the spin-orbit interaction have been calculated in
vα
SL scheme. The results would be applicable to the spectra of Nd atoms.

This paper deals with experimental methods used for the study of turbulent flow in our laboratory. They are derived particularly for the investigation of non-isotropic turbulence in a wind tunnel experiment. We show methods of measuring
u’-,
v’-fluctuation, and
u’
v’-correlation coefficient, including the mean velocity of flow, by a hot-wire anemometer: which is particularly suitable for measuring in a small space of flow as the turbulent boundary layer. Concerning these methods, theoretical discussions and their experimental examinations are given, and an example of the measurement, experimental results on turbulent boundary layer are shown.

In the present paper the effect of intensity distribution of the magnetic field upon resolving power and solid angle is discussed. Analogous to the shimming of a cyclotron, an additional pole piece will increase the intensity without any degeneration of resolving power. Some experimental results on this Subject is given here.
