パルスNQR実験のためのコンピューター制御パルスプログラマー

摘要

We constructed a computer controlled pulse programmer for the measurement of nuclear quadrupole resonance relaxation times. Programmable interval timer 8253 was used as device for pulse programming. The circuit is very simple and construction is also easy in comparison with the usual pulse programmer. This programmer is sufficiently useful concerning the pulse programming of slimple pulse sequences such as π-τ-π/2 and　π/2-τ-π, which are usually used in the measurement of relaxation times. We tudied a Fourier Transform Spectrum and relaxation times using this pulse programmer.
