$\it{Z}$ ~ 124的超重离子在Al和U中阻止本领的估算
Evaluation of Stopping Powers of Superheavy Ions with $\it{Z}$ up to 124 in Al and U
摘要：
在0.01-0.20 MeV/u能量范围内，计算了$\it{Z}$ = 124和$\it{A}$ =300的超重离子在Al和U中的电子和核阻止本领。使用从SRIM获得的具有6个$\leq$ $\it{Z}$ $\leq$ 92的离子的阻止能力来估计相应的阻止能力。计算结果与Northcliffe和Schilling的$'$阻止本领表以及Al中$^{16}$ O和$^{19}$ F离子的实验数据进行了比较，在0.10 MeV/u以上，轻离子的电子阻止本领的估算值与实验值比SRIM数据更符合。
英文摘要：
Electronic and nuclear stopping powers of superheavy ions with $\it{Z}$ up to 124 and $\it{A}$=300 in Al and U were estimated in the energy range of 0.01-0.20 MeV/u. The corresponding stopping powers were estimated using stopping powers of ions with 6$\leq$$\it{Z}$$\leq$92 obtained from SRIM. The results were compared with those deduced from Northcliffe and Schilling$'$s stopping-power tables and with experimental data for $^{16}$O and $^{19}$F ions in Al. Estimated electronic stopping powers of the light ions agreed better with their experimental values above 0.10 MeV/u than the SRIM data.
