Isotope Studied
Data Gained For
Theory of Nuclei
Eugene - A new radioactive
isotope has been discovered
by a University of Oregon
nuclear physicist.
Dr. Bernd Crasemann, as
sociate professor of physics in
the university, who spent the
past year at Brookhaven Na
tional laboratory, has pro
duped a practical demonstra
tion of a theory that is expect
ed to give more definite in
formation on the structure
and energy of nuclei. He has
synthesized rhenium 189,
which until this time has only
been postulated.
: It has been known, Crase
mann explained, that nuclei
in a certain region of the
periodic table, including the
J'rare earths," are deformed
and would look like a foot
ball (W one could see such
small objects -as atoms and
nuclei), rather than like a
beach ball as do the other
nuclei.
Sudden Chang
: The region of deformed
;nuclei stops suddenly, with the
isotopes of the metal osmium,
and the ones that follow are
heavier and round and
smooth.. ... .- .
'i The nuclei in the "transl
'tion region," where the sud
den change from deformed to
Ixound shapes occurs, are
especially interesting to physi
cists, who believe that knowl
edge 'of nuclear structure can
.be gained by studying atoms
1n this region. Rhenium-189
ii such a nucleus or isotope.
V In I960, Crasemann, with a
U of O graduate assistant;
James G. Pengra, conducted
experiments using a cyclotron
;on the University of Califor
nia campus at Berkeley1, They
hoped to make rhenium-180
but were unsuccessful. Their
calculations predicted that the
Isotope would have a short
life-time, between one and ten
days. They also calculated that
"the life of the isotope prob
ably could not survive in the
targets shipped from Berkeley
Jo Eugene. .
1 During Crascmann's. 1981-
i2 leave from ' Oregon, the
elaborate equipment at Brook
haven, one of the world's larg
est centers for nuclear re
search, was available and he
resumed his attempts.
Working with two Brook
shaven physicists, G. T. Emery
and W. R. Kane, Crasemann
)nade further attempts to pro
duce "odd'' rhenium-189.
' Months passed before the
leam had developed tech
niques for producing measur
able amounts of the material.
'Mathod Derelopad
;. The best method they de
. ,veloped consisted of placing
tungsten foils in the interior
of the cyclotron, where they
were hit by intense beams of
high -energy alpha particles
(helium nuclei), some of which
entered the tungsten atoms
jmd stayed there, but kicked
put a proton. The Intensely
radioactive1 foils 'were re
moved from the cyclotron and
processed chemically.
i The work . had . to be done
partly by remote control, be
hind thick' walls of lead, to
protect the experi m e n t e r s
from the strong radiation.
Finally, the minute amounis
of radioactive rhenium were
electroplated on gold foils.
mat in turn .had been plated
nn copper supports. Informa
tion was then aathereri before
Ihe radioactive rhenium de
cayed away.
i One of the most inleresting
aspects of the experiments,
laid Crasemann, is that the
results were Just as expected.
They had already calculated
the probable life expectancy
ef the isotope and with what
energy it would decay and
these facts were borne out by
the experiments.
They now know, the physi
cist continued, that the liew
Isotope is a bit deformed, that
ft both vibrates and rotates,
nd that it appears to be fairlv
hard.
Jet Airliners
Have Close Call
Kansas City, Mo. -'TO- Two
jet airliners came within 100
jards of colliding head-on
ever central Kansas Tuesday
night, the Federal Aviation
Administration disclosed!
Wednesday.
The airliners.a Trans World
Airline Jet flying east from
Lob Angeles and an American
Airlines plane flying west
from St. Louis, continued their
flight without Incident after
the near collision.
,' Marshall Benedict, regional
public" affairs officer for the
FAA here, said both airliners
were flying under radar con
trol at 33,000 feet when the
Incident occurred. ....
l Benedict said the pilot nf
the TWA plane, not immedi
ately identified, saw the ap
proaching American jet and
made a slight turn to avoid
collision.
