A more detailed analysis reveals that their lifetimes increase towards the magic neutron number 184.

From Science Daily

However, the neutron number 184 is still a long way from being reached, so the 30 seconds are only one step on the way.

From Science Daily

“Most reasonable models favour this proton and neutron number to be those that should give extra stability in the region,” says Rudolph.

From Nature

“All existing data for elements 116, 117 and 118 do confirm that lifetimes increase as one goes closer to the neutron number 184, says theorist Witold Nazarewicz of Oak Ridge, who was not involved in the study. “This is encouraging.”
