【摘要】We have reported the mass measurements of neutron-deficient nuclides 79Y,81;82Zr,83;84Nb in this year’s Annual Report.However,for the N=Z nuclides close to A=80,the yield is much lower and even if they can be produced,there is still great difficult to identify them because of their

quite

similar

mass-to-charge

ratio

and

revolution

times.However,their mass are extremely important for rapid proton capture process,for example,80Zr and 84Mo are waiting points of rp-process.Their masses can greatly effect the reaction flow of proton capture on them and then the abundance of the heavier nuclides.In addition,the separation energy of 84Mo(determined by the mass of 80Zr and 84Mo)has a strong impact on the 83Nb(p,α)reaction rate and plays a key role in the formation of Zr-Nb Fig. 【总页数】2页(P.38-39)
