Many GAMMA rays (about 38) are as yet unassigned in the level 172HF2C scheme. Total unassigned intensity is AP 13% 172HF C 2. Additional levels are likely to be populated between the energy 172HF2C gap 1791 and 2450. 172HF C 3. GAMMA-ray intensity balances are inconsistent with expected 172HF2C feedings (from DJPI) for several levels 172HF CL E$From least-squares fit to EG's 172HF CL J$From adopted levels. 172HF CE IE,LOGFT$Values are considered as approximate since a GAMMA-ray 172HF2CE intensity of AP 13% associated with unplaced GAMMA rays has not been 172HF3CE accounted for and many levels have feedings which are inconsistent 172HF4CE with DJPI's 172HF CG CC(A)$Total ECC deduced from EKC. EKC value multiplied by 1.23 172HF2CG to include contribution from higher shells. The ICE(K) for these 172HF3CG lines is expected to be contributed mainly by the E0 component 172HF CG TI(B)$Relative transition intensity deduced from ICE(K). ICE(K) 172HF2CG multiplied by 1.23 to include contribution from higher shells 172HF CG 409.2 (E0) and 636.26G reported by 1973Ca10 are omitted since 172HF2CG according to erratum to 1973Ca10, these belong to 194TL decay. 194TL 172HF3CG was formed from the gold foil surrounding the target. However, 172HF4CG there is no 409.2 E0 transition known in 194TL decay. This line 172HF5CG must be some other impurity in the electron spectrum of 1973Ca10 172HF CG RI(G+-)=56 14 (1973Ca10) relative to 100 for 214G 172HF2CG refers, most likely, to the positron intensity, as suggested by the 172HF3CG GAMMA-ray spectrum given by 1973Ca10. The deduced positron intensity 172HF4CG from the present level scheme is consistent with this value 172HF CG M$CE data are normalized to KC=0.140 for 214G; mult=E2 from 172HF2CG G(THETA) in (HI,XNG) and RUL (for quadrupole transitions) 172HF CL BAND(A)$ (PI=+,ALPHA=0) GS BAND 172HF CL BAND(B)$ KPI=0+ B-BAND 172HF CL BAND(D)$ KPI=2+ G-BAND 172HF CL BAND(E)$ KPI=0+ BAND 172HF N 0.55 5 0.55 5 1.0 1.0 172HF CN NR$SUMOF((TI of G's to GS)=100, with the following assumptions: 172HF2CN 1. No direct EC,B+ feeding is assumed for 95, 309, 628, 871, 1295, 172HF3CN and 1336 levels. The coincidence data (G(G+-)) (1973Ca10) are 172HF4CN consistent with no feeding of the first two levels, whereas, 172HF5CN DJPI=3 rules out feeding of the last four levels. The in-out 172HF6CN intensity balance does suggest feeding of the last five levels, 172HF7CN but the apparent feedings can be accounted for by the unplaced 172HF8CN GAMMA intensity of AP 24 units, which might populate these levels 172HF9CN 2.
