摘　　要：在中国原子能研究院HI-13串列加速器上用束-箔技术完成了80MeVTi离子和C箔相互作用产生的高电离态离子谱观测,与用激光等离子体技术的实验结果做了比较,大多数谱线与激光等离子体技术的实验结果有较好的符合,有3条谱线是未观测到的.这几条谱线为ⅩⅧ13·406,ⅩⅧ14·987,X17·439nm,属于2s2p24P3/2—2p32D3/2,2s2p21S0—2sp31P1,4p1P0—5d1P1跃迁.The spectrum of highly ionized titanium was studied by means of the beam-foil technique. Titanium ions were provided by the HI-13 tandem accelerator at China Institute of Atomic Energy. The experimental results are compared with those of laserproduced plasmas. Numerous lines attributed to Ti ⅩⅥ to ⅩⅧ ransitions have been identified, and three of them were newly measured, which were attributed to 2s2p^24P3/2-2p^32D3/2, 2s2p^21S0-2sp^31p1 and 4p^1Po-5d^1 P1 transitions.
