在费米国家加速器的内部目标实验室中，研究了能量范围为$80l~{E}_{\mathrm{inc}}l~350$ GeV的质子撞击氪和氙目标所产生的同位素分解核碎片（${A}_{f}, {Z}_{f}$） $3l~{Z}_{f}l~14$。幂律依赖性，等压产率$\ensuremath{\propto}{{A}_{f}}^{\ensuremath{-}\ensuremath{\tau}}$，被发现描述了在广泛的产量范围内的数据。$\ensuremath{\tau}$的特定值是碎片形成机制的标志。
Isotopically resolved nuclear fragments (${A}_{f}, {Z}_{f}$), $3l~{Z}_{f}l~14$, produced by protons in the energy range $80l~{E}_{\mathrm{inc}}l~350$ GeV incident on krypton and xenon targets have been studied at the Internal Target Laboratory of the Fermi National Accelerator. A power-law dependence, isobaric yield $\ensuremath{\propto}{{A}_{f}}^{\ensuremath{-}\ensuremath{\tau}}$, was found to describe the data over a broad range of yields. The particular value of $\ensuremath{\tau}$ is a signature for the fragment formation mechanism.
