    The absorption wavemeter investigated consists of a single loop with a variable gap which is formed by a pair of parallel plates. A calibration formula for the meter was derived on the assumption that the stray capacity could be considered constant and the stray inductance negligible. This simple and useful formula was ex perimentally checked on four different meters, covering the range from about one-and-quarter meter to one-half meter.

    The absorption wavemeter investigated consists of a single loop with a variable gap which is formed by a pair of parallel plates. A calibration formula for the meter was derived on the assumption that the stray capacity could be considered constant and the stray inductance negligible. This simple and useful formula was ex perimentally checked on four different meters, covering the range from about one-and-quarter meter to one-half meter. These melors were carefully constructed and accurately calibrated with reference to a quartz oscillator by the double-heating method through the use of an auxiliary oscillator of a continuous range of wave-lengths from six to ten meters.

    By surrounding a photo-neutron source of Ra+Ee with a thin spherical sbell of paraffin, a continuous spectrum of scattered neutrons, extending from zero energy to the energies of the primary neutrons is obtained. When a silver detector is exposed to such a spectrum, a part of the neutrons having just the energies at resonance with the silver nuclei is strongly absorbed by the detector and thereby produces the induced β-activity. By measuring the activity of silver and the apparent absorption coefficient of the...

    By surrounding a photo-neutron source of Ra+Ee with a thin spherical sbell of paraffin, a continuous spectrum of scattered neutrons, extending from zero energy to the energies of the primary neutrons is obtained. When a silver detector is exposed to such a spectrum, a part of the neutrons having just the energies at resonance with the silver nuclei is strongly absorbed by the detector and thereby produces the induced β-activity. By measuring the activity of silver and the apparent absorption coefficient of the resonance neutrons in a thin silver absorber, the total width of the resonance levels effective to neutron capture and located in the above spectrum is estimated. Let τ He the average value of one half of the half-value width of the resonance levels, expressed in volts, and n be the number of resonance levels here concerned. We find nτ=260 volts for the silver nuclei of half period 22" if the energies of the primary neutrons are taken to be 2x 105 volts. Knowing nτ, we can evaluate the average spacing between adjacent resonance levels effective to neutron capture by giving a plausible value to τ. We find a spacing of the order 80-800 volts if τ be given the value 0.1-1.0 volt. This result is in good accord with the recent theoretical calculation of Bethe and also with observations of resonance groups in the low energy region.

    把‘镭—铍’所产生的‘光中子’,穿过一层半厘米厚的白蜡,我们便得到一‘连续的中子谱’。他们中间有些中子,能和银的原子核起‘共振作用’,因此可以被银片吸收,而产生‘人工放射银’先测量人工放射的强度和‘共振中子’在银片中的吸收率,再应用原子核内共振能层的宽度,我们便可以求出银的原子核内‘共振能层’的密度大约共振能在零和二十万伏特中间,平均每隔一二百伏特便有一可以吸收质子的共振能层,和理论很相符合。

    Nine Marchi series of albino rats in which various points of the retina were destroyed by the method of thermocautery have been carefully studied. The courses and the terminations of the degenerated optic fibers have been determined. The results are summarized by a composite diagram (fig. 9). It shows:(1) that the fibers issuing from the upper quadrant of the retina are lying in the lateral of the optic nerve, crossed in the lower level of the chiasma passed along the medial part of the crossed optic tract and terminated partly in the ventral of the posterior half of the lateral geniculate body and partly in the caudolateral part of the superior colliculus;(2) that those from the lower retina are lying in the lower part of the nerve, crossed in the higher level of the chiasma, passed along the lateral border of the crossed tract, and terminated partly in the dorsal part of the anterior half of the lateral geniculate body and partly in the medio-oral part of the superior colliculus;(3) that those from the temporal retina are lying in the lateral part of the nerve, crossed in the lower level of the chiasma, passing through the inner part of the tract and terminated partly in the medial part of the lateral geniculate body and partly in the lateral part of the superior colliculus;(4) that those from the nasal retina are lying in the medial of the nerve, crossed in the higher level of the chiasma, passing through the outer border of the tract and terminated partly in the lateral part HSIANG-TUNG CHANGof the anterior half of the geniculate body and partly in the medial part of the superior colliculus;(5) that those from the peripheral margin of the temporal retina are lying in the lateral half of the nerve, uncrossed in the chiasma, passing through the upper half of the tract, terminated in the central part of the geniculate body and never reached the superior colliculus; and(6) that the anterior and posterior accessory optic tracts composed probably of the collaterals of the crossed optic neurons are traced to the corpus Luysii and the nucleus opticus tegmenti respectively.(7) that the optic fibers also terminate in the pretectal nucleus of the thaIamus.
