| 摘 要： | 用虚拟自旋-1/2算符理论考察了I=1的核四极共振自旋系统在其能级间隔较小时对1-2个脉冲的响应.由于核四极相互作用表象中的射频场与核自旋的相互作用(Hrf)包含时间,因而用Dyson时序算符来计算密度算符在Hrf作用下的演化.

| Abstract: | Responses to 1-2 pulses for NQR spin system of I=1 with small energy level separation are examined with fictitious spin -1/2 operator formalism.Because the interaction of nuclear spin and radio frequency field in the framework of nuclear quadrupolar interaction is time dependent, time evolutions of density operator are calculated with Dyson time order operator. |

| Keywords: | NQR Responses to pulses Dyson time-order operator |
