However, studies by Baisden 6719 1451 23 et al, Jung et al, and Bosch indicate a value between 2.62 and 6719 1451 24 2.69 keV, and a weighted mean of 2.650(28) keV has been adopted. 6719 1451 25 An allowed EC transition of 2.650(28) keV was assumed to 6719 1451 26 populate the ground state of Dy-163. 6719 1451 27 6719 1451 28 Studies of the decay properties of Ho-163 are strongly 6719 1451 29 associated with the behaviour of bare (Dy-163)66+ ions in heavy- 6719 1451 30 ion storage rings (Jung et al, Bosch, and Klepper). Significant 6719 1451 31 changes were observed in the half-life of daughter (Ho-163)66+ 6719 1451 32 ions. Mass spectrometric measurements by Baisden et al and 6719 1451 33 Kawakami et al have produced an adopted value of 4570 years for 6719 1451 34 the neutral species. 6719 1451 35 6719 1451 36 Ho-163 undergoes electron capture through the M and higher shells 6719 1451 37 (N, O etc). The models in COGEND (A. TOBIAS DEC-1990) and the 6719 1451 38 checking code FIZCON assume that this form of decay will involve 6719 1451 39 capture from the innermost K and L shells. Hence, the ENDF-6 data 6719 1451 40 cannot be generated using COGEND or checked by FIZCON. Fractional 6719 1451 41 atomic shell electron capture probabilities calcuated using the 6719 1451 42 EC-CAPTURE code (Nichols, private communication) yield: P(K)=0.0, 6719 1451 43 P(L)=0.0, P(M)=0.1967(133), P(N)=0.6688(111) and P(O)=0.1346(23) 6719 1451 44 for the 2.650(28) keV decay to the ground state of Dy-163. Auger 6719 1451 45 and X-ray data need to be determined separately. 6719 1451 46 6719 1451 47 TEMPORARY ENDF-6 DATA PRODUCED BY PERRY & DEAN WTC (NOV 2001) 6719 1451 48 1 451 47 16719 1451 49 8 457 9 16719 1451 50 0.000000+0 0.000000+0 0 0 0 06719 1 099999 0.000000+0 0.000000+0 0 0 0 06719 0 0 0 6.716300+4 1.615290+2 0 0 0 16719 8457 1 1.44218+11 6.627100+8 0 0 6 06719 8457 2 2.650000+3 2.800000+1 1.053370-3 0.000000+0 0.000000+0 0.000000+06719 8457 3 3.500000+0-1.000000+0 0 0 6 16719 8457 4 2.000000+0 0.000000+0 2.650000+3 2.800000+1 1.000000+0 0.000000+06719 8457 5 0.000000+0 2.000000+0 0 0 6 16719 8457 6 1.000000+0 1.000000-4 2.650000+3 2.800000+1 0.000000+0 0.000000+06719 8457 7 2.650000+3 2.800000+1 0 0 6 06719 8457 8 2.000000+0 1.000000+0 1.000000+0 0.000000+0 0.000000+0 0.000000+06719 8457 9 0.000000+0 0.000000+0 0 0 0 06719 8 099999 0.000000+0 0.000000+0 0 0 0 06719 0 0 0 0.000000+0 0.000000+0 0 0 0 0 0 0 0 0
