    "abstract": "Metastability and long-range interactions of Mg, Ca, and Sr in the\nlowest-energy metastable $^3P_2$ state are investigated. The calculated\nlifetimes are 38 minutes for Mg*, 118 minutes for Ca*, and 17 minutes for Sr*,\nsupporting feasibility of cooling and trapping experiments. The\nquadrupole-quadrupole long-range interactions of two metastable atoms are\nevaluated for various molecular symmetries. Hund\u0027s case (c) 4_g potential\npossesses a large 100-1000 K potential barrier. Therefore magnetic trap losses\ncan possibly be reduced using cold metastable atoms in a stretched M=2 state.\nCalculations were performed in the framework of ab initio relativistic\nconfiguration interaction method coupled with the random-phase approximation.",
