ML_FF_SION2_MB = [real]
| Default: ML_FF_SION2_MB | = none | if ML_FF_IBROAD2_MB=1 |
| = 0.5 | otherwise |
Description: This tag specifies the width of the Gaussian functions used for broadening the atomic distributions of the angular descriptor within the machine learning force field method.
The unit of ML_FF_SION2_MB is in . Test calculations showed that a 1.5 smaller value for the broadening of the radial descriptor compared to the angular descriptor (see ML_FF_SION2_MB) gives optimal results.
