  1. The coupled equation method ( cem ) has been improved to calculate 4s subshell of mnl by adding 3d ~ ( 5 ) ( ( 4 ) ~ x ) 4s ( ( 5 ) ~ x ) channels, which were verified to play a key role to the magnitude of resonance structure due to the interaction between 4s kp transition and 3p 3d excitation. our calculation shows higher symmetry and a solo peak near 51. 7ev, which is in better agreement with experimental data than garvin ' s calculation. except 3p 3d giant resonance, there are obvious 3p nd ( n > 4 ) rydberg resonances with width in the total cross section of mnl

    在研究錳原子4s殼層的共振結構時,我們首次在耦合方程方法中加入了3d ~ 5 ( ~ 4x ) 4s ( ~ 5x )通道與大共振之間的相互作用,發現這類通道對於4s殼層的共振結構具有較大的貢獻,從而改善了在耦合方程方法中只考慮基態3d ~ 5 ( ~ 6s ) 4s ( ~ ( 7 , 5 ) s )的缺陷,為精確計算其他過渡金屬原子外殼層的共振結構做了很好的鋪墊。
