Then, by the normalization condition, \begin{eqnarray} \int g_{nl}(r) g_{nl}(r) r^2 dr \approx g_{nl}^2 \int_0^R r^2 dr = g_{nl}^2 \frac{R^3}{3} = 1 \Rightarrow g_{nl} \approx \sqrt{\frac{3}{R^3}} \ \ {\rm at} \ r \le R. \end{eqnarray} .. 더보기 6.1.4 Properties of the Radial Integrals (+Python code) In this section, our purpose is to evaluate the radial integrals in the single-particle matrix elements of the multipole operators: 2024.03.28 - [Nuclear Physics/From Nucleons to Nucleus] - 6.1.3 Single-Particle Matrix Elements of the Multipole Operators 6.1.3 Single-Particle Matrix Elements of the Multipole Operators In this posting, I derive the single-particle matrix elements of the multipole.. 더보기 이전 1 2 3 다음
