Abstract

The formalism of asymptotic normalization coefficients and methods for determining them from experimental nuclear data are discussed. A new method is proposed that uses the continuation of the modulus squared of a partial-wave amplitude. It is shown that the recently proposed \(\Delta\) method for the continuation of elastic scattering data is not strictly correct. It is argued that, unlike asymptotic normalization coefficients, the values of spectroscopic factors cannot be unambiguously determined from experimental data on nuclear reactions. The Trojan horse method is discussed, which allows one to determine cross sections of binary astrophysical nuclear reactions from the data of reactions with three particles in the final state.

散射数据，渐近归一化系数和天体物理学的解析连续性

摘要

讨论了渐近归一化系数的形式和从实验核数据确定它们的方法。提出了一种新的方法，该方法使用部分波幅度的模平方的连续性。结果表明，最近提出的延续弹性散射数据的\（\ Delta \）方法不是严格正确的。有人认为，与渐近归一化系数不同，不能从核反应的实验数据中明确确定光谱因子的值。讨论了特洛伊木马方法，该方法允许从最终状态下三个粒子的反应数据确定二元天体核反应的横截面。
