| Popis: | This is the third paper in a series giving collision rates for electron excitation of the 2 P o 1 2 P o 3 2 ground state ne-structure transition in aluminium- like ions. In this paper we give data for the tran- sitions in P iii (17.9 m), S iv (10:5 m) and Cl v (6.71 m). For the P and Cl ions the only existing results are nearly 30 years old and were obtained using a method which does not incorporate resonance eects. For S iv, previous close-coupling calculations do exist but we show that our more elaborate calculation changes the rate coecients by about 50% at lower temperatures. |
