Limits on time-reversal-violating scalar interactions

Adelberger`s analysis of time-reversal-violating (TRV) scalar weak couplings is reexamined. A little-known result, which limits TRV tensor couplings is used to remove the assumption.that the TRV tensor contribution is zero. New limits on TRV scalar couplings are obtained as shown: with about 7.5% of the previously allowed area now excluded. Adelberger`s method is also applied to improving the limits on TRV tensor weak couplings.
