Dear Denis,
I have asked Wes to share with you results of his studies of OHe molecules formation in the analogy with hydrogen molecules formation. You can also contact him directly as well as to find his BSc thesis and its discussion in the same NIRS directory on Forum (NIRS Wes Carnee). The information on dark atoms can be found in

Your first task is to take an XHe (an n-alpha-article nucleus, in which an -2n charged lapton is situated) and to check that at the XHe number density, corresponding to their explanation of the modern dark matter XHe gas was collisional in the period of XHe formation (just after Big Bang Nucleosynthesis, in which He-4 was formed).
I look forward to your first draft by the next Thursday.
Please don't hesitate to contact me on Forum or by e-mail in case of troubles
With the best regards
