چکیده
when the a particle is initially in the state i. The Sij's are determined from the relative intensity of the lines emitted in transition from that state. Take the particular case where S12 = S02 = 1/2 and (12 = #o2 = (01 1-7 13= 1/200 then P1/P2 = 4.3. This ratio is nearly the same as that of the internal conversion coefficient of y rays from RaC. There the values of this coefficient can be divided roughly into two groups whose ratio is 1 to 4. The extension of the analysis to take into account the dependence of P on the number of transitions possible from a given a particle level will account for the variation of the internal conversion factor from one state to another. Although the accuracy of the agreement cited above is probably accidental, it shows the type of dependence of this factor on the state in which the a particle may be present. Nothing further, however, can be definitely stated until the states of RaC are definitely known. 4Rutherford and Ellis, Proc. Roy. SQc., 132, 667 (1931). 2 Bramley, Proc. Nat. Acad.

fXY = fYX. Problems of this type can be multiplied indefinitely, and a general theory of partial differentiation in the large to cover all such problems is desirable. We have started to construct such a theory. Among the various theorems which we have proved are three which we announce in this note as follows. THEOREM 1. Let f(x, y) be of class C' on an open point set H. Let the four second par...

T N A R E C E N T A R T I C L E in another library journal1 I made the point that American periodicals dealers have surprisingly and, from the standpoint of good business principle, foolishly avoided telling their clientele anything about themselves. I stated that it is my great hope that the dealers themselves would correct this situation within the near future. Certainly, I should think, the ...
