Abstract

Recent accelerator experiments on fusion of various elements have
clearly demonstrated that the effective cross-sections of these
reactions depend on what material the target particle is placed in.
In these experiments, there was a significant increase in the
probability of interaction when target nuclei are imbedded in a
conducting crystal or are a part of it.
These experiments open a new perspective on the problem of so-called
cold nuclear fusion.

This seems to me, an unqualified, careful scientific layman, to be
reasonable, simple theory, citing recent experiments:

"Recent experiments on fusion of elements on accelerators

For atom-atom collisions the expression of the probability of
penetration through a Coulomb barrier for bare nuclei should be
modified, because atomic electrons screen the repulsion effect of
nuclear charge.
Such a modification for the isolated atom collisions has been
performed in H.J. Assenbaum and others [6] using static
Born-Oppenheimer approximation.

The experimental results that shed further light on this problem were
obtained in relatively recent works C. Rolfs [7] and K. Czerski [8].

Review of earlier studies on this subject is contained in the work of
L. Bogdanova [9].

In these studies a somewhat unusual phenomenon was observed:
the sub-barrier fusion cross sections of elements depend strongly on
the physical state of the matter in which these processes are taking
place.

Figure 1 (left) shows the experimental data [8], demonstrating the
dependence of the astrophysical factor S(E) for the fusion of elements
of sub-threshold nuclear reaction on the aggregate state of the matter
that contains the target nucleus 7Li.

The same figure (right) presents similar data [7] for the DD reaction,
when the target nucleus was embedded in a zirconium crystal.

It must be noted that the physical nature of the phenomenon of
increasing cross synthesis of elements in the case where this process
occurs in the conductor crystal lattice is still not completely
clear...."

"The article discusses the mechanism of DD -> He-4 fusion and
so-called nonradiative thermalization of the reaction in crystals,"
scientists in Dallas, United States report.

"The dynamics of this process is considered.
The assumption that the decay time of the compound nucleus depends on
its excitation energy makes experiments in crystals compatible with
the acceleration data," wrote E.N. Tsyganov and colleagues.

The researchers concluded:
"We consider the processes in the crystals that increase the intensity
of DD fusion in comparison to the amorphous media, and the yield of
the reaction is estimated."

Tsyganov and colleagues published their study in Physics of Atomic
Nuclei (DD Fusion in Crystals. Physics of Atomic Nuclei,
2010;73(12):1981-1989).
