This overview and collection of documents and other material
related to the Office of Scientific Intelligence (OSI) offer a
glimpse of CIA's overall contribution to the analysis of Soviet
capabilities in science and technology during the Cold War. It is
by no means intended to be definitive, or even complete, with
respect to all the activities associated with the Agency's
scientific and technological capability, analysis, and resulting
report. It does, however, highlight some key events and selected
activities that contribute to our understanding of the unique role
OSI played in the Agency's history.

Thesis. The electrical characteristics of In/I/In and In/I/Pb
superconducting tunnel junctions have been studied in detail. Since
In does not readily form pinhole free oxide layers, a thin
insulating dielectric was formed on freshly deposited In film by
passing an electric discharge through an atmosphere of fluorocarbon
gas. Junctions were then completed by depositing a thin counter
electrode of In or Pb. The same process was used to prepare high
resistance junctions with Au as the base electrode; these were not
however, studied in detail. In/I/In and In/I/Pb junctions were
produced with resistances in the range 0.01 ohms to 10/sup 10/ ohms
at liquid helium temperatures. Low resistance junctions exhibited
nonlinear electrical characteristics associated with good quality
oxide'' superconducting junctions including (a) the dc Josephson
effcct, (b) quasiparticle tunneling characteristics. (c) phonon
structure and (d) inelastic tunneling phenomena. The magnitude of
the Josephson current for In/I/In junctions agreed to within a few
percent of the value predicted by strong coupling theory. Current
voltage (I-V) and first and second derivative curves for In/I/In
and In/I/Pb were compared with curves for Al/I/In and Pb/I/Pb
junctions. Discrepancies between the characteristics can be, for
the most part, explained on the basis of existing theories of
phonon mediated superconductivity using recent data from inelastic
neutron scattering studies of In. Nonlinear structure at voltages
below the phonon spectrum was observed and is most likely
associated with Kohn singularities. At higher voltages, second
derivative curves exhibited resonances characteristic of CH and OH
impurities in the barrier as well as a complex spectrum associated
with the vibrational spectrum of the fluorocarbon dielectric. To
better characterize this dielectric, a variety of surface analytic
techniques were used to determine the complex index of refraction,
the chemical composition and chemical homogeneity of the barrier.
I-V curves for high resistance junctions were used to determine the
potential at the metal-insulator interface.

Diffusion in the silver-zinc-cadmilth system was investigated at
6000C with semi-infinite, vapor-solid couples in order to evaluate
intrinsic diffusion coefficients and interdiffusion coefficients in
the alpha and beta phases. Intrinsic diffusion coefficients were
determined at several composition points.in the alpha phase region
along concentration lines of 11 at. pct Zng 18 at. pet. Zns 5 at.
pct. Cd and 9 at. pct. Cd. Interdiffusion coefficients in the a
phase were determined at several points of intersection of various
composition paths; these composition points of intersection were
along lines of constant zinc-to-cadmium concentration ratios of
3.8, 1.8 and 1.2. All two-phase diffusion couples developed planar
B/a interfaces. Intrinsic coefficients were computed at three
composition points in the beta rega corresponding to a silver
concentration of approximately 55 at. pct. Intrinsic coefficients
for B alloys are two to three orders of magnitude larger than those
for alpha alloys.

E/B decay branching ratios were measured for decays from Eu, 14 3 1
4 39 Sm', and 1 4 39Gd. y -y triple coincidence experiments were
performed to get relative positron feedings to respective daughter
levels. X-y coincidence measurements were done for 1459Gd decay to
obtain relative electron capture feedings and these feedings were
inferred from singles intensities for 143Eu and 1439Sm decay. 143
The decay schemes of Eu and 1439Sm were also studied, and 12 143
levels were reported in Pm as well as 16 levels in 143Sm. Data were
also gathered relevant to 14ompm decay and a B+ endpoint for 66Ga
decay is reported. B decay theory is discussed in some.detail,
especially concerning the implications of E/B decay branching
ratios. It is shown that anomalous ratios can only occur for higher
order terms 'in allowed transitions or if a pseudoscalar force is
present. Neither possibilities were hitherto eliminated
experimentally. Among 15 measured /B branching ratios, two were
significantly anomalous. The transition to the 808.5 keV level in
145Eu was anomalous by a factor of 24 and the transition to the
1173.1 keV level in 143Pm was anomalous by a factor of 4.9. Each
case'involved a similar hindered.
