The single-electron wave function of the ground state of the helium atom is obtained from Hylleraas' well-known wave function by integrating the latter over the coordinates of one electron. The energy of the ground state calculated with this one-eleetron wave function is -5.717Rh. compared with the value -5.755 given by the seif-consistant field solution.

将Hylleraas 氏之著名波动函数对一个电子之各座标积分之,吾人求得正常状态氦单一电子之波动函子。由此单一电子波动函数所求得之正常状态能量为-5.717h较自身一致场的解法所求得之值-5.755Rh为大。

A variatioual calculation of the energy of the-2s2 is state of helium has been carried out with the use of a wave function of the Hylleraasian typo. The wave function is where s,t u are in units of 4 times the first Bohr radius of hydrogen. The energy iscompared with the value -1.4400 Rh obtained by the method of self-consistent field.

本文以变分法计算2s~21~S态氦原子之能量,所用之波函式,即:=e~(-0.2278s){1-0.17079s-0.063155u-0.013869t~2 +0.010044u~2+0.0064785s~2}上式中之s,t,u均以4倍於氢原子之第一Bohr半径为单位。由此所计算得之能量为 E(2s~21~S)=-1.5412Rh而由自足场方法所算得之值则为-1.4400Rh。

The quantized energy values of an electron enclosed in a spherical box are calculated by solving Schrodinger's wave equation. The energy levels are very close together if the sphere is of ordinary dimensions. But as the radius of the sphere decreases toward atomic dimensions, the value of every energy level increases and the spread between the levels also increases.

本文以波力学讨论电子在球形范围内运动时之情况。由计算得知。如球形大时,则电子之能层甚为密接,如球形之半径缩小至原子大小之程度,则其每一能层之值增大而能层与能层间之间隔亦增大。
