Rule 703.        Bases of Opinion Testimony by Experts

The facts or data in the particular case upon which an expert

bases an opinion or inference may be those perceived by or

made known to the expert at or before the hearing.  If of a

type reasonably relied upon by experts in the particular field

in forming opinions or inferences upon the subject, the facts

or data need not be admissible in evidence in order for the

opinion or inference to be admitted.  Facts or data that are

otherwise inadmissible shall not be disclosed to the jury by

the proponent of the opinion or inference unless the court

determines that their probative value in assisting the jury to

evaluate the expertís opinion substantially outweighs their

prejudicial effect.
