He, Ne and Ar isotopes have been measured in six, and 26Al in two diogenites. Cosmic-ray exposure ages corrected for shielding effects using 22Ne/21Ne ratios are generally concordant. Five diogenites have a group age of 14 Myr and three others may have a group age of 24 Myr, implying that two collisions may have produced 8 of the 9 diogenites.
