Baed on 15 chondrites with exposure ages equal to or greater than 12,000,000 a and depth profiles of Dhurmsala and Keyes, an average production rate ratio (Mn-53/Al-26)(prod) = 1.48 + or - 0.15 (dpm/kg Fe / dpm/kg Si/equ/) was calculated, which seems to be depth-independent...
Three internal friction peaks (PL,PH, andPM) were observed in theLa1.95K0.05Mo2xTxO9δsamples, among whichPLandPMare of relaxational type whilePHis associated with a kind of phase transition. The results revealed that peakPLis originated from the short-distance jumps of oxygen vacancies, ...
