We obtain spherically symmetric solutions for scalar fields with a non-minimal coupling xi absolute value of phi/sup 2/ R to gravity. We find, for fields of mass m, maximum masses and number of particles of order M/sub max/ approx. 0.73xi/sup 1/2/ M/sub Planck//sup 2//m, and N/sub max/ approx. 0.88xi/sup 1/2/ M/sub Planck//sup 2//m/sup 2/ respectively, for large positive xi. For large negative xi we find, M/sub max/ approx. 0.66 absolute value of xi/sup 1/2/ M/sub Planck//sup 2//m, and N/sub max/ approx. 0.72 absolute value of xi/sup 1/2/ M/sub Planck//sup 2//m/sup 2/.
