Abstract An explicit non-relativistic mathematical analysis of a model proposed by Vigier to interpret (within the present frame of quantum theory, i.e. in terms of spin-orbit and magnetic interactions appearing in dense media) excess heat observed in the so-called “cold fusion” phenomena based only on hydrogen is presented. The existence of new “tight” Bohr orbits is demonstrated in this case.

1. Introduction The essential idea proposed by Vigier to explain the confirmation with H,O of a set of (so-called) “nuclear cold fusion” experiments [l] rests on the fact that the quantum electron jumps in the hydrogen atom (or deuterium, tritium, etc.) from Bohr’s usual orbits with energies = 14 eV into new “tight” quantum orbits with energies = few keV (as discussed in Ref. [2]). One can try to demonstrate the existence of the new levels by introducing explicitly magnetic spinspin and spin-orbit interactions. Through a study of exact solutions of the Dirac equation [3] Barut obtained a Schriidinger equation fiq= Eyr with a potential V(r) = A/r + B/r* + C/r3 + D/r4. This result was used by Vigier to analyze the problem of the hydrogen atom with a potential different from the Coulomb one. In the present work we shall make an attempt to analyze the results obtained in Ref. [2]. It is shown that when one neglects the tensor part of

bhe forces and one limits oneself to the central spin-spin and spin-orbit forces one can write explicitly the analytical form of the radial factor of the wave function. One can then try to improve the model through a more exact study of the influence of the non central part of the interaction Hamiltonian.

2. The Barut-Vigier assumption of new “tight” energy levels

As a starting point of the Baru-Vigier model one assumes that the system of two charged spinning particles in the non-relativistic approximation can be described by the Pauli equation with a Hamiltonian which contains explicitly spin-spin and spin-orbit interactions, i.e. Hz-

Here m,, P,, e,, r,, M, are the mass, the momentum, the charge, the radius and the magnetic dipole of the first particle; mz, P2, e2, r2, M, are the same properties of the second particle. From the very beginning of our analysis, as in Ref. [2], we shall neglect the last term in (1). Let us Anow look for the solution of the Pauli equation H?lJ = EV, where 6 is given by relation (1). To do that let us introduce the following notations, P=P, r=r,

This formula differs from the one given in Ref. [2] by the two last terms. This difference is due to the neglect in Ref. [2] of the magnetic moment of one of the two particles. Since the operators i? and ( 6. t) commute, i.e. they have common eigenfunctions, one can replace the operator ( 6. fl) by its eigenvalue CT. Then one obtains

There is a set of contradictory estimates of energy values and quantum orbit-radii based on Hamiltonian (4). Hence the analytical and exact solution of the Pauli equation with Hamiltonian (4) is of great use. A similar Hamiltonian can be obtained [4] for a nonrelativistic charge e, moving in the vector potential A = p2 CTX r/r3 of another charge e2 with magnetic moment p, and p2 (see the Appendix).

One can assume for simplicity that each particle possesses a normal magnetic moment M, = (e,h/2m,c)a, and M, = (e,h/2m,c)a,. In this case the terms of the Hamiltonian can be written in the form

In general one can use this algorithm to obtain the wave-functions for n = 2, 3,. . . . But even in the case n = 1 the method meets with difficulties because one can solve Eqs. (10) and (1 I> only numerically. In the cases n > 2 similar expressions are more complicated. However, the numerical solution is possible. For example by means of the MathCad computer program a “tight” state n = 1, 1= 0, E = 40 keV has been found in addition to the usual Coulomb states ‘. The detailed analysis of this model of hydrogen atom will be continued. Namely, we shall consider the interaction with an external electromagnetic field. A paper in which the main aspects of the method applied to solve the radial Schrbdinger equation for inverse-power potentials (i.e. main results obtained in [4]) are reexposed and comments on the numerical solution are made is to be published soon. Of course in this article a non-relativistic approximate calculation with the neglect of anomalous magnetic moments of particles was presented. But following a suggestion of Vigier a Pauliitype equation can be transformed into a relativistic FeynmanGell-Mann equation by the substitution of E+ T (proper time), xi --f x~, i.e. V2 into q .

For a given sign of p,, say p2 > 0, the l/r3 term is negative only for I = J + + if e, < 0, or I = J - $ if el > 0. One expects therefore resonances for (J =- ;, Z=l),(J=+, r=2) ,... for e, 0. According to Vigier the new “tight” orbits are only possible in special types of dense media where they are built in special conditions under the influence of external magnetic fields, i.e. in electrolytic or discharge experiments.
