                         rotational failure of a parent body. Collisional asteroid families 
                         tend to be more spread in proper element domains, while young spin 
                         clusters are usually much more compact. Recently, it has been 
                         shown that young spin clusters may form at higher rates in 
                         extremely young asteroid families (families younger than 3 Myr) 
                         than in more evolved groups. Among asteroid families, the Koronis 
                         family is a natural laboratory to test this phenomenon. While the 
                         family itself is very evolved, with an estimated age of more than 
                         2 Byr, two young sub-families are known to be located among 
                         Koronis members: the extremely young family of Karin, with an age 
                         of 5.750.05 Myr, and the relatively young sub-family of 
                         Koronis(2), with an age of 105 Myr. This fact allows studying the 
                         occurrence of young spin clusters in extremely young, young and 
                         evolved asteroid populations, all sharing the same physical 
                         properties. Using methods based on backward numerical 
                         integrations, we identify one possible pair candidate in the Karin 
                         family, and retrieved the pair 1741258640 recently found in other 
                         works. No convincing spin pair candidate was found in the 
                         Koronis(2) sub-family. This suggests that the occurrence of young 
                         spin clusters in families older than 3 Myr may be a rarer event 
                         than what previously thought.",
