Pil DELTA THETAROBBED
Almost $100 was taken from the
Phi Delta Theta fraternity last night
while the members of the house were
at dinner, in the latest of a series of
fraternity robberies this year. Ann
Arbor police announced that they had
gotten fingerprints, but did not know
whether any of thin were not those
of fraternity members.

Bayley, Crane To Measure
Forees By Bombardment
Of Protons
The mysterious forces which pre-
vent the universe from spontaneous-
ly exploding into a myriad of hydro-
gen atoms and neutrons are the sub-
ject of an investigation already begun
by Mr. Donald Bayley and Dr. H. R.
Crane, of the physics department, in
their laboratory in the East Physics
Building.
These forces, the physicists explain,
which act between the minute par-
ticles composing the nucleus and bind
them together, are of a different na-
ture and thousands of times stronger
than any gravitational .or electrical
forces heretofore known. Called the
nuclear forces, these new kind of
forces are probably not due directly
to the electrical or the massive prop-
erties of the nuclear particles, but
nevertheless are inherent in all mat-
ter.
Existence of such forces was made
necessary when theoretical physicists
could not reconcile the presence of
electrons in the nucleus, which if
present would bind the nucleus to-
gether, with the fact that their elec-
trical charge would make them enor-
mous in comparison to the size of the
nucleus. Since protons, which repel
each other, and neutrons, which have
no electrical charge and 'therefore
no electrical binding forces, are be-
lieved to make up the nucleus, it was
necessary to incorporate the idea of
nuclear forces, as a property of mat-
ter, into the theoretical conception
of the composition of the atom.
Additional proof of the existence of
these forces, and measurement of
them, are being undertaken by these
local scientists. Since these forces
are confined soclosely to the nucleus,
and since the nucleus is protected by
a number of revolving electrons, it is
difficult to investigate them except by
bombardment of the nucleus itself.
The method of attack being used here
is that of bringing about collisions
between protons (hydrogen atoms
with one satellite electron removed)
which are moving at extremely high
speeds. The particular way in which
one proton bounces off the other upon
collision gives a clue as to the nature
and magnitude of the nuclear forces,
according to these Univeristy scien-
tists.
The great velocities will be given
the protons by accelerating them in
the million volt vacuum tube now be-
ing installed in the East Physics Bldg.
under the direction of Dr. Crane.
"At first the observation of the col-
liding protons seems difficult; because
these particles are 100 million times
too small to be seen with the most
powerful microscope," said Mr. Bay-
ley.
"Fortunately, however," he con-
tinued, "protons produce charged par-
ticles, known as ions, along the path
they traverse in a gas, and under
proper conditions water can be made
to condense on these charged particles

lation and see to it that at the cru-
cial hour the government adhered
to that legislation.
Suggests Measures
The measures he suggested pass-
ing were as follows: (1) A law pro-
hibiting trade in war supplies. (2)
A law prohi1iting the extension of
credits and loans to warring na-
tions. (3) A law providing that any
citizen who took himself or sent goods
into a war zone did so on his own re-
sponsibility.
He emphasized, however, that all
legislation is useless unless when the
time comes to put that legislation in-
to effect, "we have enough under-
standing, organization and political
power to support and force the ad-
ministration of those laws."
just as it does on dust particles when
a fog is pi oduced. In this way, a
line of water drops is formed along
the path of the proton and under in-
tense illumination this shows as a
white streak. This can easily be
photographed and a permanent rec-
ord of the journey of the proton is
thus obtained."
The apparatus for producing the
cloud tracks is known as a Wilson
cloud chamber.1
A collision between two protons ap-
pears as a sharp bend or a fork in
the fog streaks and the angle at which
one particle bounds oif another can
be measured, Mr. Mayley added. From
the numbers of protons which bound
off at various angles, valuable infor-
mation about the nuclear forces which
come into play during the collisions
can be obtained. Although the angle
of rebound varies from 0 to 180 de-
grees, a determination of the rela-
tive numbers which deflect at each
angle enables one to calculate the
forces which are acting upon the col-
liding particles.
At the present time the cloud cham-
ber for this work is completed and
running, and actual measurements
will be started as soon as the million
volt vacuum tube is completed. Fur-
ther experiments are also planned by
Mr. Bayley and Dr. Crane in which
the million volt tube is used merely
as a trigger for releasing still higher
speed protons from boron nuclei. This
is done by shooting deutron projec-
tiles at a target of boracic acid, which
contains boron.
From these experiments it is ex--
pected by these physicists that inter-
esting and highly important results
will be obtained since such high speed
protons have never been used before.

3Youths Intent
Upon Salva"in1
Whiskey Cargo
FRANKFORT, Mich., May 7. -('P)
- Three Milwaukee youths, intent
upon salvaging the whiskey cargo of
the steamer Westmoreland and $100,-
000 in gold reported to have gone
down with the vessel when she found -
ered in a Lake Michigan storm 81
years ago, began a survey today in an
effort to locate the sunken hulk of the
steamer.
The government is expected to
claim a $2 a gallon tax on the long-
aged whisky if any of the 350 barrels
are recovered, and the 'Treasury De-
partment likely will claim any gold
the salvage operations produce.
Browne, joined in the search by
Ervon Bierck, Milwaukee automobile
salesman, who owns the salvage tug
Patricia, and Carl Moore, Milwaukee,
designer of a treasure seeking device,
said he would not start worrying
about claims until the treasure is lo-
cated.
"The Government, under the
banking laws, should exchange cur-
rency for any gold we find," he said,
"and the whiskey will be worth $20 a
quart. I can't see where I'm going
to lose."
