We have used selective excitation and monitoring of individual (J,m/sub J/) Zeeman sublevels of the 4 /sup 2/P/sub 1/2/ and 4 /sup 2/P/sub 3/2/ states of K at 22 kG and 131 kG to measure (J,m/sub J/..-->..J', m/sub J/') transition cross sections for K colliding with He, Ne, and Kr at 380 K. The results, translated into irreducible tensor cross sections for depolarization are, in units of 10/sup -16/ cm/sup 2/: /sup 2/P/sub 3/2/; ..lambda../sup 1//sub 3/2/(He) = 97 +- 13; ..lambda../sup 2//sub 3/2/(He) = 130 +- 17; ..lambda../sup 3//sub 3/2/(He) = 99 +- 23 ..lambda../sup 1//sub 3/2/(Ne) = 103 +- 10; ..lambda../sup 2//sub 3/2/(Ne) = 146 +- 14; ..lambda../sup 3//sub 3/2/ (Ne) = 111 +- 14 ..lambda../sup 1//sub 3/2/(Kr) = 270 +- 24; ..lambda../sup 2//sub 3/2/(Kr) = 341 +- 29; ..lambda../sup 3//sub 3/2/(Kr) = 276 +- 30 /sup 2/P/sub 1/2/; ..lambda../sup 1//sub 1/2/(He) = 45 +- 5 ..lambda../sup 1//sub 1/2/(Ne) = 56 +- 6 ..lambda../sup 1//sub 1/2/(Kr) = 81 +- 6. The measured total cross sections for intramultiplet transitions, sigma/sup 0//sub 1/2/(/sup 2/P/sub 1/2/..-->../sup 2/P/sub 3/2/) and sigma/sup 0//sub 3/2/ (/sup 2/P/sub 3/2/..-->.. /sup 2/P/sub 1/2/), are, in units of 10/sup -16/ cm/sup 2/: sigma/sup 0//sub 1/2/(He) = 36.5 +- 9.5; sigma/sup 0//sub 3/2/(He) = 18.7 +- 7 sigma/sup 0//sub 3/2/(Ne) = 5.9 +- 2.6 sigma/sup 0//sub 3/2/(Kr) = 25 +- 7
