[1] This was the first time in sixty-nine years that a new element had been claimed to be discovered in nature, after Marguerite Perey's 1939 discovery of francium.

[3] A criticism of the technique, previously used in purportedly identifying lighter thorium isotopes by mass spectrometry,[4] was published in Physical Review C in 2008.

[6] A repeat of the thorium experiment using the superior method of accelerator mass spectrometry (AMS) failed to confirm the results, despite a 100-fold better sensitivity.

[1] It is still possible that traces of unbibium might exist in some thorium samples, though given current understanding of superheavy elements, this is very unlikely.

[3] Amnon Marinov lived in Jerusalem, Israel with his wife Rachel; they have four children and six grandchildren.
