主　　题：pumped relaxation collision 

摘      要：Cs atoms were optically pumped with a Ti:sapphire laser in a magnetic field of 1.516 *** absorption spectra and populations of Zeeman sublevels of the ground state of Cs in N2 gas at various pressures(5,40,and 80 Torr)were *** results show that in a high magnetic field,the combined electron-nuclear spin transition(Hip-Hop transition)j which is mainly induced by the collision modification 8a(J•I)of hyperHne interaction,is an important relaxation mechanism at high buffer-gas pressures.
