The nonlinear current-voltage curves exhibited by tin films in the flux flow state have made studies of the amount of heating present in the sample necessary. The samples in this work consisted of an evaporated tin film on one side of a 2 mm thick crystal quartz substrate and a carbon film of the same configuration as the tin film on the back of the substrate. The carbon film was used as a thermometer to measure the temperature rise of the tin film above the bath temperature. The heating results indicate negligible effects in the samples. Temperature ratios as small as 0.80 for the tin samples have been investigated and the current-voltage characteristics are still nonlinear, indicating that the source of the nonlinearity is not Joule heating in the samples

THE LATTICE PARAMETERS OF NOHSO 4 and NOHS207
Carl-Friedrich Linstrdm and Joachim Loscher
Many X-ray bar graphs of NOHSO 4 [1) and NOHS 2 0 7 [2], [3) have 353
already been published. However, data are lacking on the crystal
system, the magnitude of the lattice parameters and the Miller
indices of individual X-ray interferences.
The positions and intensities of X-ray reflections have been
measure,., using Ni-filtered copper radiation (X=1.5418 R) with a
HZG 1 horizontal counter tube goniometer of the VEB (Volks Eigener
Betrieb = People's Owned Enterprise) Freiberg Precision Mechanics.
Since the compounds are very hygrosco pic, the samples had to be
masked with polystyrene foil and had to be replaced several times
during the exposure of the X-ray film diagrsm.
We used peak heights to determine the relative intensities
and set the peak height of the strongest lire equal to 10.
The indexing of the uncorrected interference positions as per
the Gattow and P:iotter procedure [4] resulted first in only inexact
lattice parameters and--as a result--(hkl) values, which still
contained certain errors. Assuming nevertheless, that the major
part of the interferences had been correctly indexed, the Miller
indices, graphically determined as per [4], were used for refining
the lattice parameters by means of a compensation calculation.
	 /354
The calculation of the theoretical line sequence from these
corrected parameters using a program written in FORTRAN 63--which
can be used upon request--and the comparison with the measured
values resulted in more exact indices. The final lattice Para-
meters and (hkl)--values wore obtained from numerous repetitions of
these steps.
