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 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。

The second method, which surpasses the first, is compared with Kirkwood's method. in the case of hexagonal lattice with neighbour interaction. Numerical work is also carried out in this case.

A new approximation method is proposed in this article for the discussion of molecular structures,and this new method includes the two well-known theories,molecular orbital theory and electron-pair bond theory as two special cases.Let a molecule have n bonds and let the ith bond be described by the anti-symmetrical two-electron bond function ψ_i(v_(2i-1),v_(2i)).(If there exist one- electron,three-electron or many-electron bonds,they can be similarly described by the corresponding one-electron,three-electron...

A new approximation method is proposed in this article for the discussion of molecular structures,and this new method includes the two well-known theories,molecular orbital theory and electron-pair bond theory as two special cases.Let a molecule have n bonds and let the ith bond be described by the anti-symmetrical two-electron bond function ψ_i(v_(2i-1),v_(2i)).(If there exist one- electron,three-electron or many-electron bonds,they can be similarly described by the corresponding one-electron,three-electron or many-electron bond func- tions.) Then the stationary state of the molecule is represented by the follow- ing wave function Ψ, where the summation is over all permutations of 1,2,……,2n except those within the interior of the functions,since each ψ_i is already anti-symmetrical.Obviously (2~n/((2n)/!))~(1/2) is the normalization factor. By quantum mechanics the energy of the molecule equals (1) here H_i,T_(ij) and S_(11)' are respectively the following three kinds of operators, (2) (3) (4) The third term of equation (1) is the exchange integral of electrons 1 and 1', while (1,2') is that of electrons 1 and 2'.According to the definition of bond functions,ψ_i may be written as (5) Substituting equation (5) into equation (1) and carrying out the integration over spin coordinates,we obtain (6) It can be easily seen from equation (6) that the combining energy of a mole- cule consists of two parts,one being the binding energy of the bonds represent- ed by the first term of equation (6),and the other being the interaction energy of the bonds denoted by the second term of that equation. If we choose certain functions φ_i~('s) involving several parameters and substi- tute them into equation (6),we may determine the values of those parameters by means of the variation principle. For the discussion of bond interaction energies,we develop a new method for the evaluation of certain types of three-center and four-center integrals.The interaction energy of a unit positive charge and an electron cloud of cylindrical- symmetry distribution may be written as (7) where (8) and R_0~2=a~2+b~2+c~2 The interaction energy of two electron clouds both of cylindrical-symmetry distributions with respect to their own respective axes is evaluated to be (9) (10) where is to sum over j from zero to the lesser value of n-2i and m, is to sum over i from zero to the integral one of n/2 and (n-1)/2,and is to sum over all cases satisfying the relation =m-j,while b_(n,n-2i) represents the coefficient of x~(n-2i) in the n th Legendre polynomial.

本文在分子结构理论方面,作了下列两点贡献:首先建议了用双电子或多电子键函数作为近似基础,来计算分子的近似能量和近似电子云分布。这样计算得来的结果,一定会比用分子轨道理论或电子配对理论好,因为它更真实的反映了分子的化学性质,同时它也包括了后两者,而以它们为特例。我们得到了分子结合能的表示式,用表示式证明了分子结合能由两部分组成:一部分是键的结合能,另一部分是键与键间的作用能。其次是建议了一种新方法,把在计算化学键相互间的作用能中遇到的一些三中心和四中心积分,还原为容易计算的二中心积分。这方法比以往所用的好,因为它计算比较简单,同时限制性也小。
