electron-pair exchange, the processes involving /?-transformations to the electron-neutrino creation or annihilation, whereas the emission of neutrino-pairs could be associated with the gravitational radiation. Since in the mesonlanguage the process (1) shouid be described as the emission of a neutral meson, whereas the process (2) corresponds to charged (positive or negative) mesons, the former il threeprocesses-hypothesis" can be now reformulated in the following way. The exchange forces between nucleons {and also their magnetic momenta) are due exclusively to the exchange of neutral mesons, whereas all the processes connected with charged mesons (such as ordinary 0-decay, iT-capture, ureaprocesses, emission or absorption of charged mesons by various nuclei, etc.) possess probabilities which are smaller by a factor of the order of magnitude 10 12 . The abovementioned discrepancy between the observed and calculated probabilities of nuclear meson-absorption seems to represent a strong argument in favor of this point of view. W E have recently 1 established the fact that the triton has the spin § and a positive magnetic moment about 1.067 times larger than that of the proton. In view of the interest in the result it seemed desirable to improve the accuracy of the ratio of the two moments. 2 In order to facilitate comparison a new sample was prepared, which, according to a density determination, contained approximately equal amounts of Hi and H 3 in the form of a 0.1 molar solution of MnS04 in water. Confirming our previous results for the spin of the triton and the sign of its moment, signals of equal sign and about equal size and shape were obtained from the two isotopes under identical radiofrequency conditions and with those values of the d.c. field at which their respective resonances were expected to occur.A highly accurate value for the relative moments of Hi and H3 was obtained by superimposing in the transmitter coil two r.f. fields of different frequencies vi and vz, delivered from independent oscillators. The receiver coil could be tuned to simultaneous response for both frequencies by two coupled resonant circuits, so that a single diode was able to detect the peak voltage of both frequencies and hence the instantaneous sum of the two signals, received from both isotopes. The original method of field modulation and representation 3 gave thus two separate signals on the screen as long as the resonance' fields for the two isotopes had still different values but were already within the sweep of the modulating field. A slight variation of v\ resulted in the merging of the two separate signals into one of about twice the size and was continued until maximum height of this signal was observed. This indicated, within a fraction of the line width, that a common value of the resonance field for the two isotopes had been reached > so that independent of this value, their gyromagnetic ratios yp and yr had to stand in the proportion of the two frequencies v\ and v%.A considerable improvement of the accuracy was o...
