%X We study the &#x03B7; &rarr; &#947;&#947; and &#x03B7; &rarr; &#960; 0&#947;&#947; decays using an extended three-flavour Nambu&#8211;Jona-Lasinio model that includes the &#8217;t Hooft instanton induced interaction. We find that the &#x03B7;-meson mass, the &#x03B7; &rarr; &#947;&#947; decay width and the &#x03B7; &rarr; &#960; 0&#947;&#947; decay width are in good agreement with the experimental values when the UA(1) breaking is strong and the flavour SU(3) singlet-octet mixing angle &#952; is about zero. The effects of the UA(1) breaking on the baryon number one and two systems are also studied.
