ML SION1

ML_SION1_MB = [real]
Default: ML_SION1_MB = 0.333333 

Description: This tag specifies the width of the Gaussian functions used for broadening the atomic distributions for the radial descriptor within the machine learning force field method.

---

The unit of ML_SION1 is in $\AA$. Test calculations showed that a 1.5 smaller value for the broadening of the radial descriptor compared to the angular descriptor (see ML_SION2) gives optimal results. The default value for ML_SION1 is chosen such that ML_SION2 becomes 0.5.
