In summary, the number 0.62 refers to a library called lwtr.62t, which is an S(a,b) library for Hydrogen in Light Water with endf 6.3 at 500 K. It can be found in "Appendix G" of the MCNP manual, but it is an older version and it is recommended to use a newer version like 7 or 8. The documentation for the library should be consulted for further information.

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

1. What is MCNP?
MCNP is a computer code used for simulating and analyzing the transport of particles through matter. It is commonly used in nuclear and radiation physics research.
2. What does the number 0.62 in MCNP refer to?
The number 0.62 in MCNP refers to the average energy of the particles being simulated. It is expressed in units of MeV (mega electron volts).
3. How is the number 0.62 determined in MCNP?
The number 0.62 is determined by the user and represents the desired average energy of the particles in the simulation. It can be adjusted based on the specific parameters and goals of the simulation.
4. What is the significance of the number 0.62 in MCNP?
The number 0.62 represents the average energy of the particles and can affect the results of the simulation. It is an important parameter to consider in order to accurately model and analyze particle transport.
5. Can the number 0.62 be changed in MCNP?
Yes, the number 0.62 can be changed by the user in order to adjust the average energy of the particles in the simulation. This allows for flexibility and customization in the modeling process.
