What this part means

The expressions on both sides represent the same quantity under the stated assumptions.

Its job in the formula

The equals sign connects the complete expression on the left with the complete expression on the right. Both sides must have compatible units.

The passage around this formula

Further out still, past the drip lines entirely in the sense of ordinary particle stability, theoretical models predict a second region of enhanced binding among the superheavy elements — the island of stability — centered on a closed neutron shell now generally predicted near N=184 , well beyond any neutron number reached by nuclei observed to date. As Yuri Oganessian, who led much of the experimental program that produced the heaviest known elements, and Krzysztof Rykaczewski put it in a 2015 review, current experiments reach only as far as N=177 , and “modern theoretical approaches, supported by new experimental data, also point to the existence of long-lived nuclei at and around the…
