Robin, Pions have such a short lifetime, does any reaction really matter ?
From: [email protected] Hi, I got all these reactions wrong, and nobody said anything! :) Pi+ + 128I -> 128Xe stable. Pi+ + 137Cs -> 137Ba Stable. Pi+ + 90Sr (HL = 29 years)-> 90Y (HL = 2.67 days) -> 90Zr stable. Pi+ + 129I -> 129Xe stable. >E.g. Pi+ + 128I -> I127. I127 is stable. > Pi+ + 137Cs (HL = 30 y) -> 136Cs (HL = 13 days -> 136Ba which is stable). > Pi+ + 90Sr (HL = 29 y) -> 89 Sr (HL = 50 days -> 89 Y which is stable). Regards, Robin van Spaandonk local asymmetry = temporary success
