Dear friend Appah Adarkwah

Now, let's dive into the neutron cross-sections. I'll give you Appah Adarkwah some approximate values for neutron cross-sections at energies of 2.5×10−3 MeV and 2.5×10−22.5×10−2 MeV for Carbon, Zirconium, and Tungsten.

### Cross-Sections at 2.5×10−3 MeV:

1. **Carbon (C)**:

- σC​≈0.0025barns (B)

2. **Zirconium (Zr)**:

- σZr​≈0.18barns (B)

3. **Tungsten (W)**:

- σW​≈4.5barns (B)

### Cross-Sections at 2.5x10-2 MeV:

1. **Carbon (C)**:

- σC​≈0.006barns (B)

2. **Zirconium (Zr)**:

- σZr​≈0.4barns (B)

3. **Tungsten (W)**:

- σW​≈7.5barns (B)

These values are rough estimates and can vary depending on nuclide composition, isotopic abundance, and specific energy spectra. For precise data, you Appah Adarkwah should refer to nuclear data libraries like ENDF/B, JENDL, or other relevant databases.
