    "abstract": "We propose an experimental implementation of matter wave amplification by\noptical pumping (MAO) with metastable calcium atoms. First experimental results\nindicate that pumping rates can be significantly higher than in previous\nexperimental schemes and let it appear promising that the threshold condition\nfor generation of degeneracy can be reached.",
