' Hr mRHicxN Dxity FRIDAY, MAY 8, 1938 FRIDAY, MAY 8, 1931) nuclear Forces Holding Matter Together Will Be Investigated Classirie Dhu-eeiory 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. WATCH FOR Jacobson's Announcement on Sunday's Society Page READ THE WANT ADS 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 Lansbury Hints At World State In Peace Talks (Continued from Page 1) 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. .EVENING RADIO PROGRAMS 6:00--WJR Jimmie Stevenson.

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." s I ®EflDIES MOTHER5 DAY Two Pounds $1.00 MICH IGAN All Comedy Double Bill! for RATES..
