SUMMARY
The number 0.62 in MCNP refers to the lwtr.62t library, which is an S(a,b) library for Hydrogen in Light Water, specifically associated with ENDF/B 6.3 at a temperature of 500 K. Users should consult "Appendix G" of the MCNP manual relevant to their version for accurate material and temperature references. While lwtr.62t is derived from an older version, it is recommended to use MCNP version 7 or 8 for updated data. The discrepancy in temperature references highlights the importance of checking the specific documentation for the library in use.
PREREQUISITES- Understanding of MCNP (Monte Carlo N-Particle Transport Code)
- Familiarity with ENDF/B (Evaluated Nuclear Data File/B) libraries
- Knowledge of S(a,b) libraries and their applications
- Access to the MCNP manual and relevant appendices
- Review the MCNP manual, particularly "Appendix G" for your specific version
- Explore the differences between MCNP versions 6, 7, and 8
- Study the structure and usage of ENDF/B libraries
- Investigate the implications of temperature variations in nuclear data libraries
Researchers, nuclear engineers, and physicists working with MCNP simulations, particularly those involved in neutron transport calculations and material property assessments.

To find a list of materials and temperatures, you need to look in "Appendix G" of the MCNP manual for the version of the code you are using.
I don't know what version of the code you are using, but lwtr.62t is from ENDF/B 6.3 (1993).
This is pretty old, I would use version 7 or possibly 8.
Looking at an older version of "Appendix G", lwtr.62t refers to 600 K

Looking at the version of Appendix G distributed with my version (LA-UR-17-20709), lwtr.62 refers to 500 K.
You need to look at the documentation distributed with your library.

lwtr.62t refers to 500 K not 600 K
strange ...
