Abstract
We study the weak production of Delta (i.e., e(-)+p-->Delta(o)+ nu(e) and e(+) +p-->Delta(++)+<(nu)over bar>(e)) in the intermediate energy range corresponding to the Mainz and TJNAF electron accelerators. The differential cross sections sigma(theta) are found to be of the order of 10(-39) cm(2)/sr, over a range of angles which increases with energ y. The possibility of observing these reactions with the high luminosi ties available at these accelerators, and studying the weak N-Delta tr ansition form factors through these reactions is discussed. The produc tion cross section of N(1440) in the same kinematic region is also es timated and found to be smaller than the Delta production cross sectio n. [S0556-2813(98)04005-9].
