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.

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.

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。
