Abstract

Excited metastable atoms like H (2S), He ( 21S)  and He ( 23S) are examined in terms of various radial and momentum space properties and also the Compton profile J (Q). Quantitative differences as compared to their ground state counterparts are also discussed here. The physical significance of this study is also indicated. The obtained results for metastable atoms also lead us  towards the scaling law  Radius × ionization energy = Constant.
