Abstract

It is stated that the conjecture that the hydrogen-like atoms may have large permanent electric dipole moments is doubtable. Two kinds of experiments are suggested to check the reliability of the conjecture further.

Reply to Comment on ``Permanent Electric Dipole Moment of an Rb Atom''

Huang Xiangyou, You Pei-Lin

The result of our experiment on Rb atoms is interesting and surprising. To affirm or to refuse the result should not be by conjectures but by experiments.

The authors investigate long-range Cs${}_{2}$ molecules consisting of a ground-state and a Rydberg atom, and measure and calculate permanent molecular electric-dipole moments showing that the sign of the dipole moment is negative, reflecting a deficiency of Rydberg-electron density near the ground-state constituent

Two puzzling problems in explanation of the linear Stark effect of hydrogen atom and space quantization of the dipole moment

Pei-Lin You, Xiang-You Huang

The linear Stark effect for the first excited state of the hydrogen atom shows that, in the unperturbed states, the atom has a permanent electric dipole moment (EDM) of magnitude 3eao (ao is Bohr radius). The EDM is not induce by the external field but is inherent behavior of the atom. But the calculation of quantum mechanics tells us that unperturbed states of hydrogen atom have no EDM! In the effect, two of four states have no energy shift. What are the EDM of the hydrogen atoms in the two states? Quantum mechanics can not answer the problem. The statement that the EDM of the two states is perpendicular to the field only comes from guesses in quantum mechanics. The two problems had puzzled physicists for more than 80 years. By introducing a new parameter this article gives a satisfactory explanation for the effect. Our calculation discovered that, in the unperturbed states, the atoms not only have EDM with 3eao but also can have only three directions of quantization! It is an entirely unexpected discovery. This research is a vital clue that not all is well with quantum mechanics. We prophesy that hydrogen-like atoms, such as K, Rb and Cs atom etc, may have large EDM of the order of magnitude eao in their ground state (see arXiv:0809.4767, arXiv:0810.0770 and arXiv:0810.2026).
