Although its direct detection was hindered by strong signal interference with 245Bk, the existence of a new isotope was proven by the growth of the decay product 248Cf which had been previously characterized.
Deși detectarea directă a fost împiedicat de interferențe de semnal puternic de la 245Bk, existența unui nou izotop a fost dovedită prin creșterea produsului dezintegrat, 248Cf, care a fost caracterizat în prealabil.
