A new Arxiv paper perhaps related to LENR -
"X-ray laser pulses from solids"

ABSTRACT: In experiments on irradiation of metal surfaces by ions of keV energy, X-ray laser radiation
was observed despite population inversion was unexpected. The radiation continued after the
bombarding by ions was switched off. In this paper unusual properties of that X-ray radiation are
analyzed. Anomalous states are formed inside the metal. These states are associated with narrow
potential well created by the local reduction of zero point electromagnetic energy. This reminds the
van der Waals potential well. States in the well are long-living which results in population inversion
and the subsequent laser generation observed.
The author speculates that LENR may be due to up-conversion of low energy quanta into
nuclear excitations.
