We measured the variation of the decay rate of 7Be implanted in Pd and Au host materials by detecting the 478 keV γ ray emitted from deexcitation of the first excited state of 7Li which is produced by EC decay of 7Be with two HPGe detectors simultaneously,and found that the decay rate of 7Be in Pd is larger than that in Au by(0.
将HI-13串列加速器次级束流线产生的放射性核素7Be分别注入到Pd和Au中,利用两个高纯锗探测器同时测量7Be EC衰变核素7Li第一激发态放出的478 keVγ射线产额随时间的变化,发现7Be在Pd中的衰变率比在Au中大(0。

We measured the variation of the decay rate of 7Be implanted in Pt and Al host materials by detecting the 478 keV γ-ray emitted from the first excited state of 7Li which is produced by EC decay of 7Be with two HPGe detectors simultaneously,and found no difference of 7Be decay rate in Pt from that in Al within our experimental error (<0.
14%)没有发现7Be衰变率在Pt与Al中有明显差别,讨论了这两种材料的电子亲和势及有效电子密度与EC衰变率的关系。

It is suggest that the particle is the molecular state constructed by xc1 and ρ0;the molelular state model is applied to interpret the reason why the decay rate of Y(4260)→π+π-J /ψ is much larger than that of Y(4260)→DD.
对新发现的Y(4260)粒子进行了初步研究,提出该粒子是cχ1和0ρ构造的分子态,并利用分子态模型解释了为什么Y(4260)→π+-πJ/ψ的衰变会比Y(4260)→DD的衰变率大许多,同时预言伴随Y(4260)存在2个同位旋三重态。
