dc.descriptionWe fully support the interpretation of Prof. F. Steglich, reported recently in Phys. Rev. Lett. 91 (2003)156401, that the observed \textit{below} Kondo temperature, Electron Spin Resonance (ESR) in a heavy fermion metal YbRh2Si2 is associated with the Yb3+ moment, more exactly with the strongly-correlated 4f13 configuration. We derived the ground-state eigenfunction Gamma_7^1= 0.803|\pm 3/2>+ 0.595|\mp 5/2> - 0.026|\mp 1/2> - 0.008|\pm 7/2> and crystal field parameters: B20= +14 K, B40= +60 mK, B60= -0.5 mK, B44= -2.23 K and B64= -10 mK with a small orthorhombic distortion B22= +0.23 K, that perfectly reproduce the observed ESR values of gperp= 3.561 and gpar= 0.17. These parameters also describe the observed overall temperature dependence of the paramagnetic susceptibility and predict anomalous temperature dependence of quadrupolar interactions.
