High-pressure behavior of some binary 1:1 actinide-arsenide compounds

In the present investigation the B1–B2 phase transition pressure in four binary 1:1 actinide-arsenide compounds has been predicted. The calculated compression curves and values of different high pressure properties for these compounds viz: ThAs, UAs, NpAs and PuAs are reported and compared with the experimental values. The calculated values of elastic properties show predominantly ionic nature of these compounds. The results achieved in the present study are found in good agreement with the available experimental data.
