3- The first ionization coefficient a for a certain gas is given approximately by a/p = 14 exp (- 240p/E) where p is the pressure in torr and E the electric field in V/cm. Find the value of E for maximum %3D electron multiplication at a pressure of 3 torr and the multiplication then obtained between electrodes 5 cm apart.
