热致密物质中团簇丰度的量子统计计算

Quantum statistical calculation of cluster abundances in hot dense matter

Gerd Ropke

摘要:

集群丰度计算从量子统计方法考虑到在介质中的校正。对于任意团簇大小的自能和泡利阻塞位移被认为是。对温度为$T=5$ MeV、重子密度为$\varrho=0.0156$ fm $^{-3}$的对称物质进行了探索性计算,并与太阳元素分布进行了比较。结果表明,由于泡利阻塞效应,质量数为$4<A<12$的弱束缚核的丰度被强烈抑制。

英文摘要:

The cluster abundances are calculated from a quantum statistical approach taking into account in-medium corrections. For arbitrary cluster size the self-energy and Pauli blocking shifts are considered. Exploratory calculations are performed for symmetric matter at temperature $T=5$ MeV and baryon density $\varrho=0.0156$ fm$^{-3}$ to be compared with the solar element distribution. It is shown that the abundances of weakly bound nuclei with mass number $4<A<12$ are strongly suppressed due to Pauli blocking effects.
