The CP parameters {epsilon} and {epsilon}{sup {prime}}/{epsilon} are calculated in the aspon model of spontaneous CP violation, a model which solves the strong CP problem. A new range for the scale of spontaneous breaking of CP is found. It is shown that {epsilon}{sup {prime}}/{epsilon} is suppressed by {approximately}x{sup 2}v{sup 2}/({kappa}{sup 2}thinspsin{sup 5}thinsp{theta}{sub C}){approximately}5{times}10{sup {minus}3} relative to the standard model. If experiment finds that {epsilon}{sup {prime}}/{epsilon} is 10{sup {minus}4} or greater in magnitude, it will mean that the present approach to spontaneous CP violation is excluded. {copyright} {ital 1998} {ital The American Physical Society}
