We answered to a similar question during ICCF17 as follows:
At the beginning someone from our R&D team suggested the idea to "excite" atomic hydrogen into its Rydberg state and then to build a proper environment/geometry to polarize the RSH atoms towards the NAE in order to perform a controlled reaction. Instead of characterizing such an idea as a nonsense and drop it (as we did with several others), we decided:
a. To do the maths, using existing models proposed in the literature, to check if this is feasible. Three (out of many) important of such literature references have been listed in the reference section of the paper we presented in ICCF17.
b. We built a test apparatus to find out the best (for our purpose) method to "excite" atomic hydrogen to its Rydberg state, using known plasma techniques in the literature, avoiding the laser based techniques for technical and cost/effective reasons
c. We checked the "production" of RSH atoms in this test apparatus and some important of RSH produced atom characteristics, using fluorescence spectroscopy and zero kinetic energy (ZEKE) photoelectron spectroscopy (with the help of an expert lab we work with in this field).
d. Based on the results of c above, we checked various configurations of the components and geometry of test apparatus to define the one that fit better to our mathematical models
e. Finally we moved the most suitable configuration into our Hyperion lab reactors that they were then equipped with a "triggering" mechanism for the LENR using RSH atoms, as described in the paper we released in ICCF17. Hyperion lab reactors are equipped with a "spy eye" (as you can see in Appendix of the paper we presented in ICCF17) in order to perform periodic spectroscopy checks on indicators of such RSH atoms "behavior" in their environment during LENR.
What followed was engineering, micro-engineering and material solving problems.
