213PO 217RN A DECAY 22NDS 202203
213PO H TYP=FUL$AUT=M. S. Basunia$CIT=NDS 181, 475 (2022)$CUT=1-Jan-2022$
213PO c |a|g: no (7735|a)(|g,L| x ray) (1961Ru06).
213PO c Another |a peak at 7.50 MeV with an intensity of 0.1% was observed
213PO2c by 1961Ru06. The energy difference from the 7741-keV |a, including
213PO3c the recoil, yields 243 keV for the level energy, if the 7500-keV |a
213PO4c is from {+217}Rn decay. The first excited state in {+213}Po has been
213PO5c observed at 293 keV in {+213}Bi decay. The observed |a peak at 7.50
213PO6c MeV may be due to an impurity; no positive identification could be
213POxc made by 1961Ru06.
213PO cA HF Using r{-0}({+213}Po)=1.5632 {I26}, unweighted average of
213PO2cA r{-0}({+212}Po)=1.5658 {I6} (assuming 1.56580 {I59} in 2020Si16 -
213PO3cA listed as 1.5658 {I59}) and r{-0}({+214}Po)=1.5606 {I7} (2020Si16).

213PO2cA in 1982Bo04 is increased by 2 keV, as recommended by 1991Ry01 for a
213PO3cA change in calibration energy) and 7735 {I4} (1961Ru06). Other measured
213PO4cA values: E|a=7740 {I10} (2018Sa45 - 7.74 MeV {I1}), 7740 {I30} (1951Me10
