16.14 For the scalar-field perturbation φ(t) → φο(t) + δφ(t,x), show that, to first order in 86, the perturbed parts of the scalar-field energy- momentum tensor are given by ST° = ³;(86), STO &T° = −ФФ+ Фоðф+V'&ф, 8T = $²0-680 +V'dø, where V' = dv/dø and the remaining components either follow from symmetry or are zero.
