Measurements of the magnetic field penetration depth $\lambda$ in the ternaryboride superconductor Li$_2$Pd$_3$B ($T_c\simeq7.3$ K) have been carried out bymeans of muon-spin rotation ($\mu$SR). The absolute values of $\lambda$, theGinzburg-Landau parameter $\kappa$, and the first $H_{c1}$ and the second$H_{c2}$ critical fields at T=0 obtained from $\mu$SR were found to be$\lambda(0)=252(2)$ nm, $\kappa(0)=27(1)$, $\mu_0H_{c1}(0)=9.5(1)$ mT, and$\mu_0H_{c2}(0)=3.66(8)$ T, respectively. The zero-temperature value of thesuperconducting gap $\Delta_0=$1.31(3) meV was found, corresponding to theratio $2\Delta_0/k_BT_c=4.0(1)$. At low temperatures $\lambda(T)$ saturates andbecomes constant below $T\simeq 0.2T_c$, in agreement with what is expected fors-wave BCS superconductors. Our results suggest that Li$_2$Pd$_3$B is a s-waveBCS superconductor with the only one isotropic energy gap.Comment: 6 pages, 7 figure
