✦ Synopsis

Synchrotron rndiatmn from the Stanford positron electron acLelcrator ring (SPEAR) WA\ used to CxcitL: the ups (tz i 1) F G.itc4 in Kr 01 = 4) :~i Xe (tt = 5). Utihration of the cxccllcnt time Wucturc ot ttus taclhty made po551ble rhe l1r\r dlrzcr mcd\urcmcnts of the hfctimcs of these states. The results for Kr arc (ml1 conptin:: notation): ~(55[ 3121 1) = 3.18 + 0.12 II, T(SS[ l/2] 1) = 3.1 I .C 0.12 11s; tar XC. r(6[ 3/2] 1) = 3.46 + 0.09 115; r(65[ l/2] 1) = 3.44 + 0.07 nr. In .dtlitmn the llfctmx of the Xe 5p5 [3/2] .%_I[ 3121 J = 1 \tatr: w&15 found to 'De 1.40 2 0.07 114. rffects dnc to r:ldl:ltlon tr:lppmn .IW d1rcu\5ed. * This results in d rcvcrsal of the time axis in fig. 2. It is necessary to avoid rext-time countmg losses of the time-to-amplitude converter.
