172IR H TYP=FUL$AUT=BALRAJ SINGH$CIT=ENSDF$CUT=31-DEC-2015$
172IR c 2014An10: {+176}Au produced in {+141}Pr({+40}Ca,5n),E({+40}Ca)=208,
172IR2c 212 MeV reaction using UNILAC accelerator and SHIP separator at GSI.
172IR3c Measured E|a, I|a, E|g, I|g, (implants)|a correlations, |a|g and |a|a
172IR4c correlations using 300 |mm thick 35x80 mm{+2} 16-sided position-
172IR5c sensitive 16-sided Si detector, and three tof detectors to distinguish
172IR6c between reaction products and scattered beam particles. Gamma rays were
172IR7c detected using a 4-crystal Clover Ge detector with a lower detection
172IR8c threshold of |?20 keV photon energy.
172IR cA $A 6228 {I10} |a group reported by 1984ScZQ and assigned to |a decay of
172IR2cA {+176}Au to a 168.4,(5-) level in {+172}Ir has been interpreted by
172IR3cA 2014An10 (also in 2004GoZZ) as due to 6117|a+ce sum line seen at
172IR4cA 6222 keV by 2014An10 in the decay of 1.36-s {+176}Au decay.
172IR5cA A 6260 {I10} |a group reported by 1975Ca06 has not been confirmed in
172IR6cA other |a-decay studies.

172IR3cA (deduced from interpolation of neighboring even-even nuclei), and
172IR4cA assuming y=0 for parent and daughter nuclei. 2014An10 give
172IR5cA values normalized to 1 for |a to 175.2+y level
172IR cG $A 168.4|g with proposed M2 multipolarity in 1984ScZQ is not
172IR2cG confirmed by 2014An10
172IR cG M$From considerations of observed intensities of K-x rays of Ir
172IR2cG as compared to the photon intensities of 175.2|g and 211.6|g from
172IR3cG the decay of high-spin isomer of {+176}Au, and 126.3|g and 151.5|g
