The intramultiplet mixing processes of Zn(43PbJe) by collisions with 4He and 3He were studied by employing pulsed laser techniques. The following cross sections were obtained: Zn(4 3P1) + 4He→Zn(43P2) + 4He: 3.1; Zn(43P1) + 4He→ Zn(43P0) + 4He: 1.5; Zn(43P 1) + 3He→Zn(43P2) + 3He: 4.7; Zn(43P1) + 3He-Zn(4 3P0) + 3He: 1.8; in units of 10-17 cm2. A quantum close-coupling calculation was carried out by assuming various interaction potentials. The cross sections for the production of Zn (43P2) from Zn (43P1 ) could be well reproduced by the calculation for both 4He and 3He. On the other hand, the calculated cross sections for the production of Zn (4 3P0) were found to be always smaller than the experimental ones.
