49CR cP E,J,T From {+49}Cr Adopted Levels
49CR cP QP From 2003Au03
49V c Produced by {+50}Cr(n,2n) at 14 MeV (1973Ok01, 1975Ja17), {+46}Ti(|A,n)
49V 2c at 19 MeV (1973Ok01) and 15 MeV (1974Ta11), and I(|g+ce)(|a,xn) at 20
49V Xc MeV (1953Cr18).
49V c 1973Ok01 measured |g's and |g|g's, |g|g(t) (NaI), and |b{++}'s (scin).
49V 2c |g|g's failed to confirm any of the high energy lines
49V cG 1974Ta11 and 1975Ja17 measured |g's with tantalum and lead
49V 2cG absorbers, respectively.
49V c Others: see 1995Bu23
49V cL E Calculated by the evaluator using least-squares adjustment
49V 2cL procedures, except as noted
49V cL J,E(A),T(B)$From the Adopted Levels. J|p arguments based on log|
49V 2cL {Ift}'s and data from (|a,p|g) are consistent (1974Ta11). E(level)'s
49V 3cL held fixed in least-squares adjustment procedures
49V cG I|g(|g{+|+})=3480 {I70} (1975Ja17), 3270 {I160} (1974Ta11),
49V 2cG and 3340 {I340} (1973Ok01) relative to I|g(90.6|g)=1000 {I2}
49V cG Coincidences on drawing from 1973Ok01 and 1954Nu07 (NaI).
49V cG E From 1975Ja17 for E|g<1500 and from 1974Ta11 for E|g>1500,
49V 2cG except as noted.
49V cG RI Relative photon intensity. From 1975Ja17 for E|g<2 MeV
49V 2cG and from 1974Ta11 for E|g>2 MeV (upper limits cited by 1975Ja17
49V 3cG consistent), except as noted
49V cE See 1987Mi18 for calculations of > matrix elements
49V cE IB,IE,TI From |SI|g(1+|a)(in)-|SI|g(1+|a)(out) for each state
49V 2cE and theoretical |e/|b{++}, except for g.s. feeding which is from
49V 3cE 0.5I|g(g{+|+})-|S(I|e+I|b)(to first 2 excited states) and theoretical
49V 4cE |e/|b{++}
49V N 0.0532 19 1 0.0532 19
49V cN NB$See comments on I|g normalization and |D(|g-normalization)
49V cN NR$From I|g(|g{+|+})=3480 {I70} relative to I|g(90.6|g)=1000
49V 2cN {I2} (1975Ja17), theoretical |e/|b{++} to g.s. and first two excited
49V 3cN states, and |SI(|g+ce)+I|e+I|b (to g.s.)=100
49V cN NR$Overall |g efficiency curve uncertainty of 2% added in
49V 2cN quadrature to normalization uncertainty
49V cN BR From {+49}Cr Adopted Levels
49V PN 3
49V cG M,CC From the Adopted Gammas. Others: |a(exp)(63|g)|?0.14,
49V 2cG |a(exp)(91|g)|?0.06 and |a(exp)(153|g)|?0.16 (1954Nu07; NaI, mag spect)
49V DG KC,LC,MC: FROM Adopted Gammas
49V cG RI(A) 1975Ja17 and 1974Ta11 suggest that the 601 and 663 peaks
49V 2cG observed by 1973Ok01 resulted from pileup of |g{+|+} pulses with 91|g
49V 3cG and 153|g pulses while the 1021|g resulted from pileup of two |g{+|+}
49V xcG pulses
49V cG E(B),RI(D)$From the Adopted Gammas; not observed in |b{++} decay. I|g
49V 2cG obtained from adopted branching ratios and present decay scheme
49V cG E(E) These gammas were observed to have the same T{-1/2} as for
49V 2cG {+49}Cr |b{++} decay (1975AvZV; {+46}Ti(|a,n))
