The temperature dependences $C(T)$ and $\\kappa(T)$ of the two compounds are similar to the results of a number of s-wave superconductors. Furthermore, the concave field responses of the residual $\\kappa$ for BaNi$_2$As$_2$ rules out the presence of nodes on the Fermi surfaces. We postulate that fully gapped superconductivity could be universal for Ni-pnictide superconductors. Specific","authors_text":"A. Subedi, C. F. Miclea, D. J. Singh, E. D. Bauer, F. Ronning, H.
