text: research isotope 245Cm can be obtained from the α-decay of 249Cf, and the latter isotope is produced in minute quantities from the β−-decay of the berkelium isotope 249Bk.
text: While the isotopes of seaborgium that are produced have been isolated, the quantities are so tiny that many of the chemical traits of seaborgium remain unknown.
text: While later 1958 experiments noted that new isotopes could be produced from mercury, thallium, lead, or bismuth impurities, the scientists still stood by their conclusion that element 102 could be produced from this reaction, mentioning a half-life of under 30 seconds and a decay energy of (8.8 ± 0.5)
text: The isotopes of nobelium are mostly produced by bombarding actinide targets (uranium, plutonium, curium, californium, or einsteinium), with the exception of nobelium-262, which is produced as the daughter of lawrencium-262.
text: The most commonly used isotope, 255No, can be produced from bombarding curium-248 or californium-249 with carbon-12: the latter method is more common.
