126CS c 1976Pa11: {+115}In({+16}O,5n){+126}La |e decay, {+121}Sb({+11}B,6n),
126CS2c {+133}Cs(p,8n), chem, E|g, |g|g, ce, |b|g.
126CS c Others: 1975Pa10, 1973Bl08.
126CS c The decay scheme is that proposed by 1976Pa11 on the basis of
126CS2c |g|g and E|g sums.
126CS cG E From 1976Pa11.
126CS cG RI From I|g in {+126}Cs |e+|b; decay, I|g measured in {+126}Ba
126CS2cG for {+126}Cs and to {+126}Xe source in equilibrium. See {+126}Cs
126CSxcG |e+|b{++} decay.
126CS cG E(A) Assignment to {+126}Ba decay is not certain (1976Pa11).
126CS cG E(B) Not included in authors' table, but shown as a tentative
126CS2cG placement in authors' decay scheme (1976Pa11).
126CS cG E(C) This |g is seen in |g|g coin spectra of Ba decay and
126CS2cG is included in the Ba decay scheme although 1976Pa11 lists it
126CS3cG as belonging to Cs.
126CS cG RI(D) From |g|g-coin (1976Pa11).
126CS cG M From |a(K) data of 1976Pa11 based on relative I|g and
126CS2cG I(ce(K)) data normalized so that |a(K)(388.6|g in {+126}Xe) has the
126CS3cG theoretical E2 value, unless otherwise noted.
126CS cL E From a least-squares fit to the E(|g's) by evaluators
126CS cL J From the adopted levels
126CS cE IE,TI$From inensity balances at each level, except for the ground
126CS2cE state feeding. Note that transition multipolarities are not generally
126CS3cE known so the imbalances are from I|g data only. Inclusion of internal
126CS4cE conversion would make only small differences.
126CS cE TI(X) From equilibrium condition for the chain decay of
126CS2cE {+126}Ba - {+126}Cs - {+126}Xe.
126BA P 0.0 0+ 100 M 2 1681 16
126CS N 0.408 32 1.0 1
126CS cN NR from I(|e+|b{++} to g.s.)=31% {I6}; from equilibrium
126CS2cN condition for the chain decay of {+126}Ba - {+126}Cs - {+126}Xe; see
126CSxcN {+126}Cs |b{++} decay.
