| 摘 要： | 在Origin等数据处理软件中,当实验数据较少时,自由参数的不同初始化设置会导致较大的结果差异,这为物理结果的确定带来较大不确定性.通过最小二乘法分析了345MeV/u ~(78) Kr+~9Be反应中产生的丰质子同位素的截面和结合能,并得到线性回归方程.通过回归方程,利用结合能预报部分丰质子核素的截面,以及通过实验截面对近质子滴线核素的结合能进行反预报测量.这对于近质子滴线的丰质子核素实验测量具有较好的借鉴意义.

| Abstract: | For the data analysis softwares such as Origin,when the experimental data is not enough,the initializing of parameters leads to a large difference in the fitting results.To determine the binding energies of some near proton drip-line isotopes,a least squares method(LSM)was introduced to analyze the correlation between the cross sections and binding energies of isotopes.The linear regression equation for the isotopes measured in the 345 MeV/u ~(78) Kr+~9 Be reaction was obtained by the LSM,based on which the cross sections and the binding energies of near proton drip isotopes were obtained. |
