Abstract
The role of a capillary array as a molecular beam source for use in re coil ion momentum spectrometry in ion-atom collisions is investigated. Numerical simulations show that by using a capillary array it is poss ible to obtain a half-width of 1 meV at room temperature, while the se nsitivity could be in the range as low as 100 mueV. Preliminary measur ements with electron impact ionisation showed the effectiveness of thi s technique by providing an energy resolution of about 2 meV at room t emperature, which is superior to the resolution reported using a gas c ell cooled to 30-degrees-K.
