对相对论性重核碎片动量分布宽度理论公式的改进

Improvement on Momentum Distribution Formula of Relativistic Heavy Ion Fragments

根据Ｈ．Ｆｅｓｈｂａｃｈ和Ｋ．Ｈｕａｎｇ关于核碎片动量分布的理论计算和新的假设，可以得到一个新的关于相对论性核碎片的动量分布公式，该式与实验结果符合较好，它可以大体上解释碎片质量Ｋ≤Ａ／２时的实验结果。

A new formula about the momentum distribution width of relativistic heavy ion fragments can be obtained by equally dividing the number of nucleons A in the fragmenting nucleus into groups and using the result derived by H Feshbach and K. Huang. The new formula can explain the quantity of fragments which mass number K≤A/2.
