|2.1: Decay Data|
|85Y gamma intensity|
|I was studying the decay data of 85Y nucleus in the http://hpngp01.kaeri.re.kr web site. In case of the decay of ground state, the gamma energy of 231.65 keV is included in the list of emitted gamma rays but its relative intensity is not given ( - ). Does it mean that its value is zero (unmeasureably small) or is there any other reason?
|You are right. The gamma is not measureable from b+ decay even though there is evidence for the gamma from electron capture decay of Y-85m.
