AbstractThe decays ψ⊃′→γπ0, γη and γη⊃′ are studied using data collected with the BESIII detector at the BEPCII e⊃+e⊃- collider. The processes ψ⊃′→γπ0 and ψ⊃′→γη are observed for the first time with signal significances of 4.6σ and 4.3σ, respectively. The branching fractions are determined to be B(ψ⊃′→γπ0)=(1.58±0.40±0.13) ×10⊃-6, B(ψ⊃′→γη)=(1.38±0. 48±0.09)×10⊃-6, and B(ψ⊃′→γη⊃ ′)=(126±3±8)×10⊃-6, where the first errors are statistical and the second ones systematic. © 2010 The American Physical Society.

<description.abstract>The decays &#968;&#8835;&#8242;&#8594;&#947;&#960;0, &#947;&#951; and &#947;&#951;&#8835;&#8242; are studied using data collected with the BESIII detector at the BEPCII e&#8835;+e&#8835;- collider. The processes &#968;&#8835;&#8242;&#8594;&#947;&#960;0 and &#968;&#8835;&#8242;&#8594;&#947;&#951; are observed for the first time with signal significances of 4.6&#963; and 4.3&#963;, respectively. The branching fractions are determined to be B(&#968;&#8835;&#8242;&#8594;&#947;&#960;0)=(1.58&#177;0.40&#177;0.13) &#215;10&#8835;-6, B(&#968;&#8835;&#8242;&#8594;&#947;&#951;)=(1.38&#177;0. 48&#177;0.09)&#215;10&#8835;-6, and B(&#968;&#8835;&#8242;&#8594;&#947;&#951;&#8835; &#8242;)=(126&#177;3&#177;8)&#215;10&#8835;-6, where the first errors are statistical and the second ones systematic. &#169; 2010 The American Physical Society.</description.abstract>
